The Scripture in Isa. 11: is part of the answer to this question. You did good in finding that.
Now I just need to caution you about one thing which is utmost importance in coming to the truth of the Word. It is VERY important to only say Scripture the way it is stated in the Book. If......IF you change it one bit, you will make it be twisted to something which is NOT meant,,thereby causing you to learn error.
When you say Jesus is the completeness of the Godhead......this is changing what is actually stated and meant. The reason people change these kinds of verses it to try to get the Scripture to say what they think it is supposed to say... for their church taught it to them wrong.....so they must try and make it fit......but truth of it is....it DOES NOT FIT.
Now the truth of this is the Word says that in Jesus dwells all the fullness of the Godhead BODILY.
This is only stating that God the Father GAVE Jesus the very same power and authority which God himself has........after the resurrection of Jesus. (Jesus being a human man, had this power of God inside himself.)
It is not saying that Jesus is the completeness of the Godhead. No, the Word teaches that God is the HEAD of Jesus. You cannot change this. Head......means the authority over him.
Now, it has been a while since I asked this question. Since no one picked up on it, I had forgotten it. Thank you for bringing this back up. So, let's name the seven spirits of God:
Isa. 11: 2--
# 1. The Spirit of the LORD = God the Father's Spirit.
Jesus said the Spirit of the Lord God is UPON me, for He hath anointed ME.
# 2. the spirit of wisdom and understanding
#3. the spirit of counsel and might
# 4. the spirit of knowledge and.....
# 5. the fear of the LORD
# 6. the Holy Ghost....Mark 1:10...the Spirit as a dove decended upon Jesus.
# 7. the Spirit of TRUTH. John 14:17.
Now the Word says that all seven of these spirits was upon Jesus......that is those seven eyes.
You gave a good answer to this.
