God has made a way, and that way is to believe on his Son. God didn't send his son to condemn the world, Jesus came to save us. Jesus Christ, we receive no condemnation. If you do not believe on Jesus Christ, you are condemned already. Jesus Christ is the light of the world.
Man naturally gravitates toward the darkness as the result of sin in their lives.
Verse 20 Man hates to expose their lives to the light. Those who believe in Jesus Christ are an open book, allowing God to examine every nook and cranny of their minds and hearts. If you are in the light, Jesus Christ, you will allow him to prompt and direct everything you do. Your deeds will begin with him, and he will accomplish them through you. He will direct your path.
