Devotional Scripture:  Acts 9:10-17

Introduction

Lesson Background and Key Verse

Background from the NIV Standard Lesson Commentary

Isaiah began his prophetic ministry about 200 years after the nation of Israel divided. In 931 BC, the united monarchy of Israel split into two parts: Israel (the northern kingdom) and Judah (the southern kingdom). Isaiah’s ministry focused on the southern kingdom of Judah, as reflected by the Judean kings listed in Isaiah 1:1. Surprisingly, the Lord’s call on Isaiah doesn’t occur until Isaiah 6. This is at variance from the usual pattern of recording a prophet’s call at or very near a book’s beginning (examples: Jeremiah 1:4-19; Ezekiel 1:1-3:15). Perhaps the writer wanted to establish the context of the call, which the first five chapters of Isaiah accomplish. The people of Judah had become a “sinful nation,” being openly rebellious against the Lord (Isaiah 1:1-5). A sense of self-sufficiency accompanied a facade of economic prosperity, military security, and religious arrogance (2:7-8). The Lord depicts his people as a vineyard that produced unacceptable fruit (5:1-7). In their doing of injustice, they had redefined the terms good and evil (5:20). Such was the era that Isaiah found himself in when his call came about.

 

Key Verse: Isa 6:8

Also I heard the voice of the Lord, saying: "Whom shall I send, and who will go for Us?" Then I said, "Here am I! Send me."

 

Major Theme Analysis

(Scriptural Text from the New King James Version; cross-references from the NIV)

Isaiah's Vision  (Isa 6:1-4)

 

1 In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lifted up, and the train of His robe filled the temple.

2 Above it stood seraphim {seraphs}; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew.

3 And one cried to another and said: "Holy, holy, holy is the Lord of hosts; The whole earth is full of His glory!"

4 And the posts of the door were shaken by the voice of him who cried out, and the house was filled with smoke.

 

Majesty of God (1)

God is majestic because nothing can contain Him (I King 8:27)

"But will God really dwell on earth? The heavens, even the highest heaven, cannot contain you. How much less this temple I have built!

God is majestic because there is nowhere we can go from His presence (Ps 139:7-10)

7 Where can I go from your Spirit? Where can I flee from your presence?  8 If I go up to the heavens, you are there; if I make my bed in the depths, you are there.  9 If I rise on the wings of the dawn, if I settle on the far side of the sea, 10 even there your hand will guide me, your right hand will hold me fast.

God is majestic because there is no one or thing like Him (Exod 15:11)

"Who among the gods is like you, O LORD? Who is like you-- majestic in holiness, awesome in glory, working wonders?

God is majestic because of His great power and strength (Eph 1:18-21)

18 I pray also that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in the saints,  19 and his incomparably great power for us who believe. That power is like the working of his mighty strength, 20 which he exerted in Christ when he raised him from the dead and seated him at his right hand in the heavenly realms, 21 far above all rule and authority, power and dominion, and every title that can be given, not only in the present age but also in the one to come.

God is majestic because He is worthy and deserves it (Rev 4:8-11)

8 Each of the four living creatures had six wings and was covered with eyes all around, even under his wings. Day and night they never stop saying: "Holy, holy, holy is the Lord God Almighty, who was, and is, and is to come."  9 Whenever the living creatures give glory, honor and thanks to him who sits on the throne and who lives for ever and ever, 10 the twenty-four elders fall down before him who sits on the throne, and worship him who lives for ever and ever. They lay their crowns before the throne and say:  11 "You are worthy, our Lord and God, to receive glory and honor and power, for you created all things, and by your will they were created and have their being."

 

Praise of God (2-4)

God must be praised because of His acts of power and greatness (Ps 150:1-6)

1 Praise the LORD. Praise God in his sanctuary; praise him in his mighty heavens.  2 Praise him for his acts of power; praise him for his surpassing greatness.  3 Praise him with the sounding of the trumpet, praise him with the harp and lyre,  4 praise him with tambourine and dancing, praise him with the strings and flute,  5 praise him with the clash of cymbals, praise him with resounding cymbals.  6 Let everything that has breath praise the LORD. Praise the LORD.

God must be praised because of His righteousness (Ps 7:17)

I will give thanks to the LORD because of his righteousness and will sing praise to the name of the LORD Most High.

God must be praised because He counsels and instructs us (Ps 16:7)

I will praise the LORD, who counsels me; even at night my heart instructs me.

God must be praised because He is our rock, fortress and deliverer (Ps 18:2-3)

2 The LORD is my rock, my fortress and my deliverer; my God is my rock, in whom I take refuge. He is my shield and the horn of my salvation, my stronghold.  3 I call to the LORD, who is worthy of praise, and I am saved from my enemies.

God must be praised because He lives (Ps 18:46)

The LORD lives! Praise be to my Rock! Exalted be God my Savior!

God must be praised because of His mercy (Ps 28:6-7)

6 Praise be to the LORD, for he has heard my cry for mercy.  7 The LORD is my strength and my shield; my heart trusts in him, and I am helped. My heart leaps for joy and I will give thanks to him in song.

God must be praised because it is fitting (Ps 33:1-4)

1 Sing joyfully to the LORD, you righteous; it is fitting for the upright to praise him.  2 Praise the LORD with the harp; make music to him on the ten-stringed lyre.  3 Sing to him a new song; play skillfully, and shout for joy.  4 For the word of the LORD is right and true; he is faithful in all he does.

God must be praised because He is our hope (Ps 42:5)

5 Why are you downcast, O my soul? Why so disturbed within me? Put your hope in God, for I will yet praise him, my Savior and  my God.

 

Isaiah's Call to Service  (Isa 6:5-8)

 

5 So I said: "Woe is me, for I am undone! Because I am a man of unclean lips, And I dwell in the midst of a people of unclean lips; For my eyes have seen the King, The Lord of hosts."

6 Then one of the seraphim flew to me, having in his hand a live coal which he had taken with the tongs from the altar.

7 And he touched my mouth with it, and said: "Behold, this has touched your lips; Your iniquity is taken away, And your sin purged."

8 Also I heard the voice of the Lord, saying: "Whom shall I send, And who will go for Us?" Then I said, "Here am I! Send me."

 

Recognition of unworthiness (5)

Recognizing the sin in our life makes us unworthy (Luke 5:8)

When Simon Peter saw this, he fell at Jesus' knees and said, "Go away from me, Lord; I am a sinful man!"

Recognizing that we have put others before God makes us unworthy (Matt 10:37-38)

37 "Anyone who loves his father or mother more than me is not worthy of me; anyone who loves his son or daughter more than me is not worthy of me; 38 and anyone who does not take his cross and follow me is not worthy of me.

Recognizing that we have preferred earthly thing instead of God makes us unworthy (Matt 22:8)

"Then he said to his servants, 'The wedding banquet is ready, but those I invited did not deserve to come.

Recognizing that we may have rejected God makes us unworthy (Acts 13:46)

Then Paul and Barnabas answered them boldly: "We had to speak the word of God to you first. Since you reject it and do not consider yourselves worthy of eternal life, we now turn to the Gentiles.

 

Cleansing by God (6-7)

Cleansed by shedding of Jesus blood (Heb 9:22)

 In fact, the law requires that nearly everything be cleansed with blood, and without the shedding of blood there is no forgiveness.

Cleansing of acts that lead to death (Heb 9:13-14)

13 The blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that they are outwardly clean. 14 How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!

Cleansed by coming near to God (James 4:8)

Come near to God and he will come near to you. Wash your hands, you sinners, and purify your hearts, you double-minded.

Cleansed by focusing on and doing righteousness (Isa 1:16-17)

6 wash and make yourselves clean. Take your evil deeds out of my sight! Stop doing wrong, 17 learn to do right! Seek justice, encourage the oppressed. Defend the cause of the fatherless, plead the case of the widow.

Cleansed by the word of God (1 Tim 4:5)

for it is sanctified by the word of God and prayer.

Cleansed by the Holy Spirit (1 Cor 6:11)

And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.

Cleansed by our heart being sprinkled by God through faith (Heb 10:22)

let us draw near to God with a sincere heart in full assurance of faith, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water.

Cleansed by the blood of the Lamb (Rev 7:14)

I answered, "Sir, you know." And he said, "These are they who have come out of the great tribulation; they have washed their robes and made them white in the blood of the Lamb.

 

The appropriate response (8)

Making ourselves available (Here I am)

Available by first giving ourselves to God (2 Cor 8:5)

And they did not do as we expected, but they gave themselves first to the Lord and then to us in keeping with God's will.

Available by submitting to God (2 Chron 30:8)

Do not be stiff-necked, as your fathers were; submit to the LORD. Come to the sanctuary, which he has consecrated forever. Serve the LORD your God, so that his fierce anger will turn away from you.


Available by offering ourselves to God as an instrument of righteousness (Rom 6:13)

Do not offer the parts of your body to sin, as instruments of wickedness, but rather offer yourselves to God, as those who have been brought from death to life; and offer the parts of your body to him as instruments of righteousness.

Available by living to the Lord because we belong to Him (Rom 14:8)

If we live, we live to the Lord; and if we die, we die to the Lord. So, whether we live or die, we belong to the Lord.

Available by honoring God with our body (1 Cor 6:19-20)

19 Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own; 20 you were bought at a price. Therefore honor God with your body.

Becoming a living sacrifice and servant of God (Send me)

By offering our whole self to God (Rom 12:1)

Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God-this is your spiritual act of worship.

By being renewed daily inwardly (2 Cor 4:16)

Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day.

By continually offering to God a fruit of the lips which should be a sacrifice of praise (Heb 13:15)

Through Jesus, therefore, let us continually offer to God a sacrifice of praise-the fruit of lips that confess his name.

By being a living stone in the spiritually house of God (1 Peter 2:5)

you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ.

By being a slave of righteousness (Rom 6:16)

Don't you know that when you offer yourselves to someone to obey him as slaves, you are slaves to the one whom you obey-whether you are slaves to sin, which leads to death, or to obedience, which leads to righteousness?

 

Hezekiah’s Life Extended (Isa 38:1-5)

 

1 In those days Hezekiah was sick and near death. And Isaiah the prophet, the son of Amoz, went to him and said to him, "Thus says the Lord: 'Set your house in order, for you shall die and not live.'"

2 Then Hezekiah turned his face toward the wall, and prayed to the Lord,

3 and said, "Remember now, O Lord, I pray, how I have walked before You in truth and with a loyal heart, and have done what is good in Your sight." And Hezekiah wept bitterly.

4 And the word of the Lord came to Isaiah, saying,

5 "Go and tell Hezekiah, 'Thus says the Lord, the God of David your father: "I have heard your prayer, I have seen your tears; surely I will add to your days fifteen years.

 

Isaiah’s message of death (1)

Message of death unless there is repentance (Jer 18:7-8)

7 If at any time I announce that a nation or kingdom is to be uprooted, torn down and destroyed, 8 and if that nation I warned repents of its evil, then I will relent and not inflict on it the disaster I had planned.

Message of death where God relents (Jonah 3:4-10)

4 On the first day, Jonah started into the city. He proclaimed: "Forty more days and Nineveh will be overturned." 5 The Ninevites believed God. They declared a fast, and all of them, from the greatest to the least, put on sackcloth. 6 When the news reached the king of Nineveh, he rose from his throne, took off his royal robes, covered himself with sackcloth and sat down in the dust. 7 Then he issued a proclamation in Nineveh: "By the decree of the king and his nobles: Do not let any man or beast, herd or flock, taste anything; do not let them eat or drink. 8 But let man and beast be covered with sackcloth. Let everyone call urgently on God. Let them give up their evil ways and their violence. 9 Who knows? God may yet relent and with compassion turn from his fierce anger so that we will not perish." 10 When God saw what they did and how they turned from their evil ways, he had compassion and did not bring upon them the destruction he had threatened.

Message of death where God allows time for replacement (Deut 31:14)

14 The Lord said to Moses, "Now the day of your death is near. Call Joshua and present yourselves at the Tent of Meeting, where I will commission him." So Moses and Joshua came and presented themselves at the Tent of Meeting.

Message of death because there is a time for death (Eccl 3:2)

2 a time to be born and a time to die, a time to plant and a time to uproot,

 

Hezekiah’s prayer (2-3)

A prayer that seeks God’s compassion (Ps 116:3-5)

3 The cords of death entangled me, the anguish of the grave came upon me; I was overcome by trouble and sorrow. 4 Then I called on the name of the Lord: "O Lord, save me!" 5 The Lord is gracious and righteous; our God is full of compassion.

A prayer that results in the power of God being invoked (Acts 4:29-31)

29 Now, Lord, consider their threats and enable your servants to speak your word with great boldness. 30 Stretch out your hand to heal and perform miraculous signs and wonders through the name of your holy servant Jesus." 31 After they prayed, the place where they were meeting was shaken. And they were all filled with the Holy Spirit and spoke the word of God boldly.

A prayer that is effective and fervent (James 5:16)

16 Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man is powerful and effective.

A prayer that is done in the day of trouble (Ps 50:15)

15 and call upon me in the day of trouble; I will deliver you, and you will honor me."

 

God’s answer of prayer (4-5)

A prayer that can be answered before it is spoken (Isa 65:24)

24 Before they call I will answer; while they are still speaking I will hear.

A prayer that is answered to fulfilled for those who seek God (Matt 7:7-8)

7 "Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. 8 For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened.

A prayer that is answered because it is according to God's will (1 John 5:13-15)

13 I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life. 14 This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us. 15 And if we know that he hears us — whatever we ask — we know that we have what we asked of him.

A prayer that is answered because of belief (Matt 21:21-22)

21 Jesus replied, "I tell you the truth, if you have faith and do not doubt, not only can you do what was done to the fig tree, but also you can say to this mountain, 'Go, throw yourself into the sea,' and it will be done. 22 If you believe, you will receive whatever you ask for in prayer."

 

Conclusion and Other Thoughts

Commentary Thoughts from Allen Ross

I. Revelation: The revelation of the glory of the LORD (6:1-5)

A. The LORD reveals His glory (1-4).

Verse 1 begins the report of the heavenly vision in the year that King Uzziah died. Several points from the Hebrew text need to be noted here. The first would be the use of the verb “saw” (wa’er’eh from ra’ah); this is not the word for the “seer” of visions, but the ordinary word “to see” or look at something. This suggests Isaiah is very much awake and physically observing this sight.

The object of the sight is “the Lord”—’adonay, and not the personal name Yahweh (which would be rendered “LORD”). The term signifies lord or master, the sovereign. The term “sitting” (yoshevfrom yashav) when used of God is an anthropomorphism; it means “rule,” that is, sit enthroned above. The word “throne” is actually used here; in other passages it must be understood.

The exalted nature of the Lord is presented to us with “high” (ram from rum) and “lifted up” (wenissa’ from nasa’). The physical description of His location, part of the anthropomorphic vision, is also symbolic of His nature as the “Highest”—an expression often used in the Bible for absolute sovereignty. The symbol of sovereignty, “his train,” completely fills the temple. Such is the dominance of the Lord of Glory.

Verse 2 introduces the angels. The term for angels in this order is seraphim (from saraph, “to burn”—”are they not all flames of fire?”). These are attending (literally, “standing about/over him”) the LORD as ministering servants. Their description focuses on their wings (Hebrew uses a distributive construction: “six wings, six wings to [each] one); each angel had six wings. Two covered the angel’s face—such is the nature of God that even angels blush to look at Him—two covered their bodily parts (probably a euphemism, feet meaning their central body), and with two they flew. The vision is similar to Ezekiel’s on Ezekiel 1.

Verse 3 reports what they cried continually to one another: “Holy, holy, holy is Yahweh of Armies; the whole earth is full of His glory!” This line needs a lot of attention. It is the central and turning point of the passage (as well as a prominent part in liturgy).

The word for “holy” is qadosh (s.v. qadash). A study of this word shows that it means “distinct, unique, set apart.” It does not mean “righteous”; but we use the word “righteous as well as all the other attributes to explain what holy means (i.e., in what way is God distinct from us, from angels, from pagan gods?). The description of God as holy is a major theme in the Book of Isaiah. If I may simplify it, it means there is no one like the LORD in the universe. The threefold use of the term is a Hebrew way of expressing the superlative degree—He is incomparably holy. This trisagion (as it is called, Greek for thrice holy) may harmonize with the later and full revelation of the tri-unity of the Godhead (see Isa. 48:12ff.); but it does not in itself teach the trinity.

The expression “Yahweh of Armies” must be understood. The armies are all armies—earthly or heavenly. They are all at His disposal. The use of this epithet usually introduces a judgment theme.

The other key word in here is “glory” (kavod from kavad). The basic idea of this word has to do with “weight, being heavy”; metaphorically this becomes “be important.” To describe God as glorious, if I may run the risk of oversimplification again, means that He is the most important person in the universe. The physical manifestation of His presence, the “glory of the LORD,” is metonymical for Him Himself. The words of the angels assert that the whole earth is filled with the evidence that Yahweh is the sovereign God of the universe. Isaiah’s vision concludes with the note in verse 4 of the effects of the Presence—the place shook, and was filled with smoke. This imagery is drawn from Mount Sinai and the Sanctuary.

B. The vision convicts God’s servant of sin (5).

Verse 5 gives the typical response of one who sees such a scene—struck with the knowledge of one’s own sinfulness. “Woe is me.” Hebrew “woe” (‘oy) is a wail of lamentation. It is an expression that cries out of distress, that all is lost, that grief will overtake; there is nothing that can be done.

The key word in here is “unclean” (tame’). The better that you know the Book of Leviticus the better you will understand this. It comes from the temple liturgy and ritual. To be “unclean” need not mean “sinful”; but it does mean off limits, out of bounds, unacceptable in the presence of God because of physical, earthy nature and contaminations. The focus is on the lips (here a metonymy of cause)—what he talks about is perhaps good, clean, and normal; but it is not as holy as the angels’ speech was. Question: What will we talk about in the presence of the LORD? How will our conversations change? The Bible has so much to say about speech, how it is a window to the heart. Isaiah, and the nation, are not fit to enter the Presence of the LORD—their speech betrays greater problems.

This is a critical section. Isaiah is probably the finest in the land. People often compare themselves with others and come out looking fine. The standard, however, is the glory of the LORD. There is an old saying: If you have never caught sight (literally or figuratively) of the Sublime, you have never really seen yourself.

II. Sanctification: The acknowledgment of sinfulness brings complete forgiveness (6:6,7).

The next stage in the preparation of God’s servant is sanctification, sanctification that was inspired by the vision of the glory of the LORD. What is described in verses 6 and 7 is a symbolic act; it signifies that the sin was removed. We know this is symbolic because never in the sanctuary was sin removed by searing the lips with a coal from the altar. What reality there was to this we may only surmise—it is unlikely that an angel actually took a coal and touched his lips. This is a heavenly scene and the heavenly correspondent to the coals is meant; the coals were the instrument of consuming the sacrifices that became the sin offering. The point is that the prophet was cleansed by direct divine intervention. The focus is on the lips because they represented the sinfulness of the prophet. The prophet was cleansed; the people, however, had yet to hear the word, confess, and be cleansed.

The meaning of this act is clear from the end of verse 7: “your iniquity has been removed, your sin atoned.” The term “iniquity” here probably includes all three of the categories of meaning it has—sin, guilt, and the punishment for the sin. The critical word to define here is “atoned” (tekuppar from kipper). A careful study of this word and its usage will reveal the meanings of “expiate, pacify, atone.” There is a homonym—exactly the same spelling of the root—that means “cover over.” Unfortunately, in many studies and many sermons the two have not been kept as separate words, and the idea that atonement only covers over and does not expiate has become popular. No. The sins were removed; the person was forgiven. The point here is that Isaiah’s sins were forgiven; God will not bring them up again. (The only thing that Old Testament believers did not know, and could not know, was who would ultimately pay for these sins, since they repeated sacrifices. But God knew, and on the basis of that perfect sacrifice [which, by the way, was from before the foundation of the world] He could guarantee forgiveness. They had His word on it).

III. Dedication: The removal of sin enables obedience to the call of God (6:8).

Verse 8 records the commission of the prophet in response to the Word of God. The first verb is fraught with significance: “Then I heard” (wa’eshma` from shama`). The conjunction is a “waw consecutive” that expresses the sequence: this hearing follows the preceding sanctification almost with a “so that” or “and then.” A valid point can be made that one cannot “hear” the call of God until there is sanctification. Once one is forgiven and walking with Him, one can hear His voice through His word. One has to be on speaking terms with God.

The parallelism of the word of the Lord (not LORD) is forceful: “Whom shall I send, and who shall go for us?” The call passages in the Bible all use the verb “send”; it expresses divine authentication and enablement for the mission, usually accompanied by the divine Presence. Unless the Lord sends, one cannot go with any authority.

For discussions of “for us” you can go back to the several treatments in the commentaries, and back to Genesis. It has been interpreted to mean the Lord and the angels, which is possible; it has also been taken as a plural of majesty for the Godhead that allows for the later full revelation of the nature of God.

Isaiah’s response? “Here am I, send me.” You probably will not have the time to do much with this, since the other parts are so important. And that is fine since this is easily understood. But “here am I” is a bold break-through response: “Look—me!” And then the verb is repeated, “send me.” Not “I will go.” That would be presumptuous. But “send me,” an imperative, is a request for the divine authority that goes with the mission.

Concluding Thoughts from the NIV Standard  Lesson Commentary

Not everyone will experience the same call to vocational ministry. However, God calls everyone to serve him. Regardless of where God calls us to serve, we should answer with our version of “Here am I. Send me!” When we respond humbly and willingly, God will use us to represent him to others. Some of us may serve God through vocational ministry. Others will serve him via their witness through their “9-to-5” jobs, relationships with family and friends, financial support of mission work, etc. When we follow God’s call, regardless of where it takes us, we are in a place of service to him.
