In John 8, we read that the scribes and the Pharisees brought a women caught in adultery to Jesus. To test him, they asked him if they should stone her as Moses commanded to them in the law. Jesus said to them, "Let the one among you who is without sin be the first to throw a stone at her." What a memorable response! It teaches us not to blame others at fault when we are imperfect ourselves. Only God can judge us, for he alone is holy and perfect.
