What did Jesus do?
John 8:7 tells about a woman who committed adultery and was about to be stoned to death. Jesus could have looked on her and judged her, but He didn't. He says, "one who has never sinned throw the first stone!"
This is significant because Jesus did not judge her, in fact, He did the opposite. Jesus had forgiveness and compassion for the woman.
When you catch others in sin, are you quick to judge? Or are you quick to forgive? God's role is to judge, ours is to show compassion and forgiveness.
