In the beginning was the Word, and the Word was with God, and the Word was God. (John 1:1)

Further supporting the full and unique deity of Christ, we simply observe other Scripture that consistently upholds this idea:

Before Me there was no God formed, and there will be none after Me. I, even I, am the Lord, And there is no savior besides Me. (Is 43:10–11)

Thus says the Lord, the King of Israel and his Redeemer, the Lord of hosts: ‘I am the first and I am the last, and there is no God besides Me.’ (Is 44:6)

I am the Lord, and there is no other; besides Me there is no God. I will gird you, though you have not known Me; that men may know from the rising to the setting of the sun that there is no one besides Me. I am the Lord, and there is no other. (Is 45:6)

I am the Lord, and there is none else. (Is 45:18)

Remember the former things long past, for I am God, and there is no other; I am God, and there is no one like Me. (Is 46:9)

Listen to Me, O Jacob, even Israel whom I called; I am He, I am the first, I am also the last. Surely My hand founded the earth, and My right hand spread out the heavens; when I call to them, they stand together. (Is 48:12–13)

Behold, I [Jesus] am coming quickly, and My reward is with Me, to render to every man according to what he has done. I am the Alpha and the Omega, the first and the last, the beginning and the end. (Rev 22:12–13)

For it was the Father’s good pleasure for all the fullness to dwell in Him [Christ]. (Col 1:19)

For in Him [Christ] all the fullness of Deity dwells in bodily form. (Col 2:9)

Thomas answered and said to Him, “My Lord and my God!” (John 20:28)

And He [Christ] is the radiance of His [God’s] glory and the exact representation of His nature … (Heb 1:3)

Lord Jesus, You are my Lord and my God. I worship You as the supreme Creator of the universe. Let all the angels witness my testimony.
