Their leaders are like roaring lions, tearing apart their victims. They put people to death, then steal everything of value. Husbands are killed, and many women are left as widows.
But Jesus told them: You are always making yourselves look good, but God sees what is in your heart. The things that most people think are important are worthless as far as God is concerned.
Everything is pure for someone whose heart is pure. But nothing is pure for an unbeliever with a dirty mind. That person's mind and conscience are destroyed.
