And here is the source of true kindness. The salvation of Jesus humbles us profoundly– we are so lost that he had to die for us. But it exalts and assures us mightily — we are so valued that he was glad to die for us. Because we are sinners totally accepted by grace, we have both the humility and the boldness necessary to serve others for their sake, not ours.
-- Tim Keller, from “The Grace of Kindness”
