For let me tell you this, even though you know it perfectly and be already master in all things, still you are daily in the dominion of the devil, who ceases neither day nor night to steal unawares upon you, to kindle in your heart unbelief and wicked thoughts against the foregoing and all the commandments. Therefore you must always have God's Word in your heart, upon your lips, and in your ears. But where the heart is idle, and the Word does not sound, he breaks in and has done the damage before we are aware. On the other hand, such is the efficacy of the Word, whenever it is seriously contemplated heard, and used, that it is bound never to be without fruit, but always awakens new understanding, pleasure, and devoutness, and produces a pure heart and pure thoughts. For these words are not inoperative or dead, but creative, living words. And even though no other interest or necessity impel us, yet this ought to urge every one thereunto, because thereby the devil is put to flight and driven away, and, besides, this commandment is fulfilled, and [this exercise in the Word] is more pleasing to God than any work of hypocrisy, however brilliant. The Fourth Commandment. Thus far we have learned the first three commandments, which relate to God. First that with our whole heart we trust in Him, and fear and love Him throughout all our life. Secondly, that we do not misuse His holy name in the support of falsehood or any bad work, but employ it to the praise of God and the profit and salvation of our neighbor and ourselves. Thirdly, that on holidays and when at rest we diligently treat and urge God's Word, so that all our actions and our entire life be ordered according to it. Now follow the other seven, which relate to our neighbor among which the first and greatest is: Thou shalt honor thy father and thy mother. To this estate of fatherhood and motherhood God has given the special distinction above all estates that are beneath it that He not simply commands us to love our parents, but to honor them. For with respect to brothers, sisters, and our neighbors in general He commands nothing higher than that we love them, so that He separates and distinguishes father and mother above all other persons upon earth, and places them at His side. For it is a far higher thing to honor than to love one, inasmuch as it comprehends not only love, but also modesty, humility, and deference as to a majesty there hidden, and requires not only that they be addressed kindly and with reverence, but, most of all that both in heart and with the body we so act as to show that we esteem them very highly, and that, next to God, we regard them as the very highest. For one whom we are to honor from the heart we must truly regard as high and great.
