Helping Others "Feels" Right

Why does it feel right when we help other people? I read recently that acts in which we help others, stimulate the reward centers in our brain, the nucleus accumbens & the caudate nucleus, then we feel good. That’s probably true. But consider this: Jesus was a servant. He helped others. When we help others we are being like Christ. Since that is one of the primary purposes for which we were created, it FEELS right.
