The Latin root words that form the word compassion translate as "suffer with." Jesus was the perfect example of one with authentic compassion. He truly suffered with those who were suffering, in a way that normal people could not:
Matthew 9:36: When he saw the crowds, he had compassion on them, because they were harassed and helpless, like sheep without a shepherd.
Matthew 20:34 “Jesus had compassion on them and touched their eyes. Immediately they received their sight and followed him.”
Although Jesus’ examples of compassion should be enough motivation for us to do likewise, consider that scientific research has demonstrated real, tangible feelings of pleasure are triggered in parts of the brain of those who help others. Other research has shown that humans are much more connected to others than we consciously are aware of, and hat we have a natural capacity for empathy.
When one part helps and serves another, both benefit!
