What really happens inside you when you respond to someone in need? Why do some people jump out of their seats to help another person, while others look the other way? No doubt, some people have been taught to be kind and others may be naturally thoughtful. But I think something greater than compassion or good manners is at work, something beyond the motivation of the strong to help the weak or the wealthy to help the poor. I think it is the invisible power of grace, moving between the open hearts of give and receiver. The action itself, the lifting of a heavy piece of luggage or the drink of water offered to the thirsty man, may be small. But the energy that is channeled through that action is the high-voltage current of grace. It contains the power to renew someone’s faith in himself. It even has the power to save a life.
