In John 8, some super nasty religious dudes want the people to hate on Jesus. They try to trick him into saying that a woman who’s cheated on her husband should be stoned to death. He says, ‘All right, but let the one who has never sinned throw the first stone.’ Of course they all slink away embarrassed.
Jesus assures the woman that she’s forgiven – He doesn’t condemn her – then He says, ‘Go and sin no more.’ No matter who you are and what you’ve done, Jesus forgives you. More than that, He gives you the grace and faith to leave your sin behind you, and move on free.
