What is "a Good Christian"?
In the book of Matthew, where the Judgment Day is depicted for us in the imagery of One seated upon a throne and dividing the sheep from the goats, the test of a man then is not, “How have I believed?” but “How have I loved?” . . . Sins of commission in that awful indictment are not even referred to. By what we have not done, by sins of omission, we are judged. It could not be otherwise. For the withholding of love is the negation of the Spirit of Christ, the proof that we never knew him, that for us he lived in vain. It meant that he suggested nothing in all our thoughts, that he inspired nothing in all our lives, that we were not once near enough to him to be seized with the fervency of his compassion for the world.Henry Drummond (1851–97), The Greatest Thing in the World, 57–58.
Now that is what I call challenging. A holy person is not merely someone who avoids doing evil—it is someone who does good.
