In the sermon text for this Lord’s Day, Jesus mercifully heals ten lepers. Only one of them returns to thank Jesus for his life-changing mercy. Ironically, the one who gives thanks is an outsider, a pagan. The Scriptures use leprosy as a vivid, living object lesson that illustrates the ravages of sin. The climax of the story is Jesus’ pronouncement the leper was “saved” by faith.
