John 12:44-47.
Jesus cried and said, He that believeth on Me, believeth not on Me, but on Him that sent Me.
And he that seeth Me seeth Him that sent Me.
I am come a Light into the world, that whosoever believeth on Me should not abide in darkness.
And if any man hear My words, and believe not, I judge him not: for I came not to judge the world, but to save the world.

Jesus cried and said: the sense and tense of the verb cried is that He cried out in a loud voice. This is the last instance in the book of John in which Jesus addressed the public, the multitudes that followed Him around. He spoke many more times before the final chapter, but not to the crowds.
Him Who sent Me: Jesus knew that it was His claim to be the Son of God, and God Himself, for which He would be crucified. Knowing it, though, He did not back down. He was saying, in my own words, “If you see Me, you see the Father!” To believe is to put one’s faith and trust completely in something or someone. This was Jesus’ final appeal to the public, the nation as a whole, to trust and follow Him.
I have come as a Light into the world: Not for the first time, Jesus refers to Himself as THE Light, not just A light. Walking in Him is walking in light, and not in darkness. Light sheds protection and knowledge; it reveals danger, and uncovers the evil that is done under cover of darkness.
I came not to judge the world, but to save the world: Prior to this statement, Jesus acknowledged that there would be those who would not believe on Him, and would reject Him and the Father. Jesus said, “I judge him not.” “But wait,” you may say. “Don’t the scriptures say that any who do not believe in Him will be condemned to hell? Isn’t that a judgment?”
The answer, though we may find it distasteful, is that our own choice to believe or not believe is what determines our eternal home. God has indeed created the place of eternal torment for those who choose to deny Him, and deny His Son. But it is not His desire for anyone to choose, through unbelief, to spend all of eternity in that place.
I came not to judge. . .but to save: The whole purpose of Jesus Christ coming from heaven to earth was to provide salvation, not condemnation. He chose obedience to the Father, out of love for the Father and for mankind. If He had come to condemn the world, He could have simply destroyed everything and everyone right there on the spot and saved Himself the agony of the cross. But that was not why He came.
He came to bring the Light of Life, the blessing of eternal salvation, freedom from the curse of sin and death, by giving Himself as the perfect sacrifice for all mankind.
All we have to do, to receive His gift, is believe and accept, and then flourish in the Light
