The Greek word translated "compassion" is amazingly powerful. It implies a forceful, physical reaction in a person's body in the abdominal area. It is a reaction so strong that it demands a response. A person who is "moved with compassion" cannot stand by and observe. He must do something. Why was Jesus so moved? "Because they were weary and scattered, like sheep having no shepherd" (Matthew 9:36 NKJV).
