Jesus is the human life that the Word inhabited. As a human he had no divine powers other than what the Father gave him ability to do in the moment, such as feed five thousand, walk on water, raise Lazarus from the dead, and much much more.
John goes forward to report Jesus saying things that no human can ever say, such as “I am the First and the Last,” “I forgive you your sins,” and especially, “Before Abraham was, I AM.” That last saying claimed GODhead directly because he used GOD’s actual name, I AM.
Jesus went to the cross of His own volition. He did this to take on Himself the burden of all human sin. The wages of sin is death; Jesus accepted all such wages of all people. Every human still undergoes a bodily death, but the soul can be washed clean of all its sin; this happens when a person apologizes to Jesus, and means it, and asks Him to forgive all his sins.
Because Jesus performed countless awesome miracles, because his death in the most publicly humiliating and painful manner in use at that time is foreshadowed by the 22nd Psalm, and because the faith in Jesus has spread ever since, Jesus is GOD’s final spokesperson (prophet) and my personal Savior.
