Uncle Jack frequently took an “out of the box” position on issues of common consent within the Christian community. One such issue was kindness. He wrote in The Problem of Pain:
Everyone feels benevolent if nothing happens to be annoying him at the moment. Thus a man easily comes to console himself for all his other vices by a conviction that “his heart’s in the right place” and “he wouldn’t hurt a fly”, though in fact he has never made the slightest sacrifice for a fellow creature. We think we are kind when we are only happy: it is not so easy, on the same grounds, to imagine oneself temperate, chaste, or humble.
Ouch. Lewis differentiates between active and passive kindness. Leaving others alone is not kindness, even though you do them no harm. Conversely, neither is inserting yourself in others’ business a kindness, even for the most benevolent purpose, unless, that is, you are invited. Jesus is the prime example of that sort of wisdom, illustrated in Revelation 3:20 Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me. That was the Lord’s offer to the Laodicean church, after he said they were lukewarm and about to be vomited out of his mouth.
To be redemptive people, we must follow Jesus’ example; he showed kindness to “sinners,” but was aggressive toward the self-righteous. He healed lepers, but told the lawyers they were like whitewashed tombs, full of corruption. And most of all, he showed kindness to us, carrying our sin-guilt to the cross so we could live eternally.
