Human beings judge one another by their external actions. God judges them by their moral choices. When a man who has been perverted from his youth and taught that cruelty is the right thing, does some tiny little kindness, or refrains from some cruelty he might have committed, and thereby, perhaps, risks being sneered at by his companions, he may, in God's eyes, be doing more than you and I would do if we gave up life itself for a friend.
