3:14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
3:15 That whosoever believes in Him should not perish, but have eternal life.
3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life.
3:17 For God sent not his Son into the world to condemn the world; but that the world through Him might be saved.

This morning my son smacked his sister while they were playing. I told him he was wrong for what he did and to apologize to her. The apology became a problem for him and he was punished for it. He wasn't punished for the act, but for not apologizing. This is the same concept in our everyday lives. This is the reason why Jesus was crucified for mankind. Our sin is in the acts we do but the punishment is not asking for forgiveness through Jesus the Christ. The one guarantee you have is that you will perish one day. So when your time is up, you will account to God for your sins knowingly and un-knowingly. If you confess them as they happen to Jesus, you can save yourself from God's wrath and the Bible says God will cast your sins to the depths of the sea. So you already have victory in your judgment, and having Jesus in your life gives you a life of victory with God!
