People do many good things for one another. Perhaps the highest good we can do is to put ourselves out for someone else. We are all familiar with the story of the Good Samaritan. He really put himself out for someone left beaten, robbed and half-dead.
He interrupted his journey, took are of a hurting an, and paid for his care out of his own pocket. That is dynamic caring.
He teaches us that sometimes, to really care for someone, it will cost us something.
