Before He was the Son, He was not yet created. What was the very beginning of the Father's creation?
Revelation 3:14 "And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God."
Christ is "the beginning of God's creation." Why was Christ the first thing God created?
Colossians 1:15 "He [Christ] is the image of the invisible God, the firstborn over all creation.
Colossians 1:16 For by Him [Christ] all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created by Him and for Him.
Colossians 1:17 And He is before all things, and by Him all things consist.
Colossians 1:18 And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence.
Colossians 1:19 For it pleased the Father that in Him all the fullness should dwell."
Christ was to be The Father's instrument for all the rest of His creation.
Nowhere in all of scripture, does Christ ever claim to be without a beginning. To the contrary He confesses that He is the beginning of God's creation, that His Father is greater than He, and that His Father is His God:
Revelation 3:14 "And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God."
John 14:28 "Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I."
2 Corinthians 11:31 "The God and Father of our Lord Jesus Christ, which is blessed for evermore, knoweth that I lie not."
Ephesians 1:3 "Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ."
Ephesians 4:6 "One God and Father of all, who is above all, and through all, and in you all."
1 Peter 1:3 "Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead."
God the Father created Christ to be the channel for His creation.
