Why did an omnipotent, omniscient, omnipresent Creator leave a written record for lowly men?
I believe that He had one purpose. Our Father and Creator loves us enough to reveal Himself as the suffering Messiah who came to redeem us from our sin and lost condition.
Isaiah, the prophet, clearly identifies the Messiah by stating that He would be called Immanuel, and shows us what will happen in the last days. He gives us a vision of what he sees happening in heaven, prior to Christ coming to earth.
Chapter one sets the stage. We see our sinful and lost condition as well as how an unrepentant heart separates us from our Creator. But even in our lost condition, there is hope. God tells us that we can be made clean, but only by becoming “willing and obedient.”
15 When you spread out your hands, I will hide My eyes from you; Even though you make many prayers, I will not hear. Your hands are full of blood. 16 “Wash yourselves, make yourselves clean; Put away the evil of your doings from before My eyes. Cease to do evil, 17 Learn to do good; Seek justice, Rebuke the oppressor; Defend the fatherless, Plead for the widow. 18 “Come now, and let us reason together,” Says the Lord, “Though your sins are like scarlet, They shall be as white as snow; Though they are red like crimson, They shall be as wool. 19 If you are willing and obedient, You shall eat the good of the land; 20 But if you refuse and rebel, You shall be devoured by the sword”; For the mouth of the Lord has spoken.
In chapter two, Isaiah identifies Christ as Yahweh or as most translations identify Him, the LORD. Here is a description of the millennium. I know of no church or sect who will deny that Jesus Christ will reign during the millennium.
1 The word that Isaiah the son of Amoz saw concerning Judah and Jerusalem. 2 It shall come to pass in the latter days that the mountain of the house of the LORD shall be established as the highest of the mountains, and shall be lifted up above the hills; and all the nations shall flow to it, 3 and many peoples shall come, and say: “Come, let us go up to the mountain of the LORD, to the house of the God of Jacob, that he may teach us his ways and that we may walk in his paths.” For out of Zion shall go the law, and the word of the LORD from Jerusalem. 4 He shall judge between the nations, and shall decide disputes for many peoples; and they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war anymore. 5 O house of Jacob, come, let us walk in the light of the LORD.
In Isaiah 6:1, the prophet states:
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; 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!”.
This passage indicates that Isaiah saw the Lord and He was high and lifted up and the glory of his train filled the temple. Here the Lord is called, the Lord of hosts. This person is on a throne, He is high and lifted up, He is full of glory, and He is being worshiped.
Now just who did Isaiah see? John clearly tells us in verse 41 in the following passage that when Isaiah saw “the Lord, sitting on a throne, high and lifted up”, that he saw Jesus, the Christ. Listen carefully to what John is saying here in John chapter 12.
36 While you have the light, believe in the light, that you may become sons of light.” These things Jesus spoke, and departed, and was hidden from them. 37 But although He had done so many signs before them, they did not believe in Him, 38 that the word of Isaiah the prophet might be fulfilled, which he spoke: “Lord, who has believed our report? And to whom has the arm of the Lord been revealed?” 39 Therefore they could not believe, because Isaiah said again: 40 “He has blinded their eyes and hardened their hearts, Lest they should see with their eyes, Lest they should understand with their hearts and turn, So that I should heal them.” 41 These things Isaiah said when he saw His glory and spoke of Him. 42 Nevertheless even among the rulers many believed in Him, but because of the Pharisees they did not confess Him, lest they should be put out of the synagogue; 43 for they loved the praise of men more than the praise of God.
There is no question in my mind, Isaiah saw Jesus on the throne and full of glory.
Furthermore, we get a direct indication of the Godhead with the use of the plural pronoun, “us” in Isaiah 6:8 when the words of the Lord are recorded.
8 Also I heard the voice of the Lord, saying , Whom shall I send, and who will go for us? Then said I, here am I; send me.
At this point, rather than the speaker being referred to as Yahweh, He is referred to as Adonay or Lord.
Another clear indication of the deity and identity of the Messiah comes in chapter 7.
10 Moreover the LORD spake again unto Ahaz, saying, 11 Ask thee a sign of the LORD thy God; ask it either in the depth , or in the height above. 12 But Ahaz said , I will not ask , neither will I tempt the LORD. 13 And he said , Hear ye now, O house of David; Is it a small thing for you to weary men, but will ye weary my God also? 14 Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel .
Isaiah is by no means the only prophet or the only book in the Bible that identifies Jesus as Yahweh, but a thorough read of Isaiah should be enough to eliminate any doubt a person might have.
