Have you ever known someone who blames everyone under the sun for their problems? It is much easier to blame someone else than try to improve ourselves. Instead of solving the problems in our life, we obsess over the perceived unfairness of life while not really accomplishing much else. We will never win if strive to play the blame game.
So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.
John 8:7
