We will define “godhood” as the state of being a god, just as manhood is the state of being a man. When Jesus was born, he was only and fully a perfect man. Nowhere in the Bible does it teach that Jesus was part god and part man.

Hebrews 10:5-10, “Therefore, when he came into the world, he said: “Sacrifice and offering You did not desire, but a body You have prepared for me. In burnt offerings and sacrifices for sin You had no pleasure. Then I said, ‘Behold, I have come—In the volume of the book it is written of me—to do Your will, O God.’ ” Previously saying, “Sacrifice and… offerings for sin You did not desire, nor had pleasure in them” (which are offered according to the Law), then He said, “Behold, I have come to do Your will, O God.” He takes away the first (Law Covenant) that He may establish the second (New Covenant). By that will we have been sanctified through the offering of the body of Jesus Christ once for all.”

When Jesus came to earth, he was a perfect human being just as Adam was. He became human so that he could become a substitute for Adam (1 Corinthians 15:21) and thereby redeem the whole human race. 1 Timothy 2:5,6 (NKJV), “For there is one God and one Mediator between God and men, the man Christ Jesus, who gave himself a ransom for all…” 

Hebrews 2:14, “Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil.” It is because Jesus faithfully sacrificed His will and his human body, that God raised Jesus to life immortal – which was beyond the life he previously had. 

Before Jesus came to earth, he was the Logos. John 1:14, “And the Word (Logos in Greek) became flesh and dwelt among us, and we beheld his glory, the glory as of the only begotten of the Father, full of grace and truth.” (Also note John 3:16 KJV). But the Logos was never equal with God nor was he God. He was God’s first and only directly begotten son. After God created the Logos, the Logos became God’s master builder. John 1:3, “All things were made through him, and without him nothing was made that was made.”  (See also Proverbs 8:22-31.)

However, God is and will forever be the great Author of His plan and of all creation. 1 Corinthians 8:6 (NKJV), “there is one God, the Father, of whom are all things, and we for Him; and one Lord Jesus Christ, through whom are all things, and through whom we live.”
