Beloved, heed the words of Luther below. We must be about proper instruction for the people of God and the fame of His name.
We must know how to teach God’s word aright, discerningly, for there are divers sorts of hearers; some are struck with fear in the conscience, are perplexed, and awed by their sins, and in apprehension of God’s anger, are penitent; these must be comforted with the consolations of the gospel. Others are hardened, obstinate, stiff-necked, rebel-hearted’ these must be affrighted by the law, by examples of God’s wrath: as the fires of Elijah, the deluge, the destruction of Sodom and Gomorrah, the downfall of Jerusalem. These hard heads need sound knocks.
– Martin Luther, from Tabletalk
Sound words are consoling cordials for the people of God and swift blows to those who stand in opposition to the truth.
