“My friends, in order properly to celebrate and sanctify the holy day to the praise of God, we want to preach and proclaim his dear word. For he has instituted the Sabbath so that both we who preach and you who hear should use His Word. Thereby we accord God the highest praise, and this is also the greatest service we are able to render God. And, on the other hand, nothing more irksomely pains the devil than the teaching and the using of God’s Word; and if we want to inflict the most severe injury on him, then we should diligently hear God’s Word. Besides, we surely need to strengthen ourselves with the Word of God so that we do not drown altogether in worldly cares but warm ourselves at the sermon and await another life after this one. Otherwise, when one bypasses God’s Word, one forgets yonder life and scrapes and scratches here below as though one had nothing else to do.”
Martin Luther, in What Luther Says, 1331.
