Colossians 2:9 has minimal connection with Isaiah 7:16
Brackets in passage are mine.
10 Then the LORD spoke again to Ahaz, saying, 11 “Ask for a sign for yourself from the LORD your God; make it deep as Sheol or high as heaven.” 12 But Ahaz said, “I will not ask, nor will I put the LORD to the test!” 13 Then he said, “Listen now, house of David! Is it too trivial a thing for you to try the patience of men, that you will try the patience of my God as well? 14 Therefore the Lord Himself will give YOU a sign: Behold, the virgin (not a virgin, but a young woman) will conceive and give birth to a son, and she will name Him Immanuel (this doesn't make him God). 15 He will eat curds and honey at the time He knows enough to refuse evil and choose good. 16 For before the boy knows enough to refuse evil and choose good, the land whose two kings you dread will be abandoned. Isaiah 7:10-16
- There are some parallels in Isaiah 7 with the life of Jesus, but the signs given were fulfilled in that day of the king - the sign was for him!
- Jesus did have to choose between good and evil. He did have his own will which did differ from the Father. (thereby making him not God)
- The child was named Maher-shalal-hash-baz (Is. 8:3) and he wasn't God. having the title Immanuel doesn't make someone God.
It's tempting to seize a verse here and there that aligns with our theology. This is called 'proof-texting' and it tends to ignore context and other related passages.
For in Him all the fullness of Deity dwells in bodily form
This 'fullness of deity' is an ambiguous term that is easily misunderstood on its own - we must understand it using other passages. We can liken it to having God's nature (not substance) regarding evil and goodness. God is perfectly 'good' and not evil! The fullness of being GOD cannot exist within a human body, (Moses couldn't even look at Him) but His nature can, and did, in Jesus through His spirit - just as it can in us.
We are also to have this divine nature. When we are born from above, that is all we will have. We wont be God then though, but like Him in nature and purpose.
you may become partakers of the divine nature 2 Pet 1:4
God grants Jesus his Spirit. How can Jesus be God if he is dependent on God for such an essential and inherent attribute of God, for God IS spirit, Jesus said he was not a spirit Luke 24:39. We could list the consistent passages of Jesus being a man only, but that is done in other posts.
For He whom God has sent speaks the words of God; for He (God) gives the Spirit without measure. John 3:34
Matthew 12:18 Here is My Servant, whom I have chosen, My beloved, in whom My soul delights. I will put My Spirit on Him, and He will proclaim justice to the nations.
This is quoted from Isaiah 42, a prophecy concerning the one God will send, the one He would 'choose', the one He would anoint with His Spirit Acts 10:38. Precisely because Jesus was not God, but needed God's provisions to accomplish the task set before him.
Luke 4:18 The Spirit of the Lord is on Me, because He has anointed Me to preach good news to the poor
Of course Jesus was 'filled' with God. We are to be also. How else can we be not of the world and of His kingdom if we still are full of the world?
that you may be filled to all the fullness of God. Eph 3:19
If Jesus is to be filled with God - how then could he BE God? He is either God or he is not. Because there are no verses that say he is, then we must go with that and confess Jesus as the man, the holy and sinless man sent to become the Lamb. Of course God cannot die, or be tempted or sin, so Jesus cannot be God for those things. If Jesus didn't fully die, then neither do we when baptised. If he is somehow God, then he cannot die and the whole crucifixion was a charade of some sort.
having been buried with Him in baptism, in which you were also raised with Him through faith in the working of God, who raised Him from the dead. Col 2:12
There are no contradictions in the God's word when it is read carefully and in concert with other verses. God does not inspire contradiction in His word.
Jesus was given the Holy Spirit at his baptism. He gave his spirit back to God when he died. After 3 days and nights, God raised him and drew him to His side - exalting him, making him heir to everything and judge of all.
How could Jesus be God and alleged 'creator' if he is being made heir?
He cannot be God for dozens of reasons, but he was filled with God's holy spirit or he couldn't have successfully been the Lamb.
Having the title Immanuel, Jesus was certainly 'God with us'. Just as God is with us in His word, in creation, in prayer, in spirit, in goodness and peace, He is with us through His son who had not the 'worldly' ways in him, but the Godly ways. He doesn't need to BE God, to be God with us.
