All of the book of John explains the human aspect of Jesus, although He is GOD, wrapped up in human flesh.
For example:
I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me. – John 5:30
Christ was prepared (before) the foundations of the world…to be the perfect Lamb of God. And Jesus as God, was able to live a *sinless life…which made Him the “perfect Lamb of God”, without spot, without blemish.
*No human is able to live a sinless life. Only God is able to do it.
Matthew 1:23
“Behold, the virgin shall be with child, and bear a Son, and they shall call His name Immanuel,” which is translated, “God with us.”
John 1:1-3 and vs. 14
1. In the beginning was the Word, and the Word was with God, and the Word was God. 2. He was in the beginning with God. 3. All things were made through Him, and without Him nothing was made that was made.
The Word Becomes Flesh
14. And the Word 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.
Jesus is God.
