15 Look therefore carefully how ye walk [See then that ye walk circumspectly], not as unwise, but as wise; 16 redeeming the time, because the days are evil. 17 Wherefore be ye not foolish, but understand what the will of the Lord is. 18 And be not drunken with wine, wherein is riot, but be filled with the Spirit; 19 speaking one to another in psalms and hymns and spiritual songs, singing and making melody with your heart to the Lord; 20 giving thanks always for all things in the name of our Lord Jesus Christ to God, even the Father; 21 subjecting yourselves one to another in the fear of Christ.
THE CAREFUL WALK OF THE CHRISTIAN.
1. Paul's admonition here is designed for those who, having heard the Gospel and made a fine start in believing, immediately imagine themselves secure and think they have accomplished all. Forgetful that they are still flesh and blood, and in the world and in contact with the devil's kingdom, they live in unconcern, as if delivered from all danger, and the devil far fled. By the very reason of their security they are overcome of the devil and their own flesh, and fall unawares from the Gospel. They have just enough connection with it to be able to prate of it, boasting themselves Christians but giving no indication of the fact in their conduct.
2. Paul would tell them how, in view of these things, vigilance is essential to the Christian life. To regulate the life by keeping God's will ever before the eyes, always conforming the conduct to it—this he calls walking circumspectly and being wise. If you for a moment lose sight of God's will, the devil immediately possesses you and works pernicious results, transforming a Christian into an indolent, self-secure hypocrite; a hypocrite into a heretic and factionist; and a heretic into an open enemy. So the apostle here teaches that in all seriousness if we would secure ourselves against the craft and power of the devil we must be vigilant; we must be careful how we walk. In Satan we have an enemy bent on hindering us; on undermining our very foundation.
3. Consequently they who fail to keep earnest watch over their Christian life—that is, to have a care for soundness of belief and to gladly hear and obey the Word of God—are unwise, even foolish, and have no knowledge of God's will. They have removed the light from before their eyes to behold instead a thing of their own imagination. They see as through a painted glass, presuming they do well in following such phantoms of their reason, until they are misled and defeated of the devil.
THE WORD, THE GUIDE OF THE CHRISTIAN.
4. Therefore, not without reason does Paul warn Christians to be always wise and circumspect—to keep the Word of God before them. Upon so doing depends their wisdom and understanding. Let each one make it a matter of personal concern, and especially should it be the general interest of the congregation. Where care is not observed to retain the Word in the Church, but there are admitted to the pulpit brawlers who set forth their own fraudulent doctrines, the Church is injured; the congregation will soon be as the preacher. Again, if the individual fails to regulate his daily life—the affairs of his calling—by the Word of God; if he forgets the Word and absorbs himself in accumulating wealth; if he is tangled with secular interests, he soon becomes a cold and indolent Christian, then an erring soul, and finally utterly disregards God's will and his Word.
It is for these reasons God so frequently commands us in the Scriptures continually to explain and apply his Word, to hear it willingly and practice it faithfully, and to meditate upon it day and night. He would have our lives emanate from the Word in honor to God and gratitude to him—from the Word wherein we daily look as in a mirror. But care and diligence are necessary to bring it to pass, and we should faithfully assist each other by instruction, advice, and in other ways.
5. In my admonitions I have often enough urged those who have influence, to use all diligence in drawing the young to school, where they may receive proper instruction to become pastors and preachers; and I have earnestly advised that in cases of necessity ample financial provision be made for students. But, alas, few communities, few States, are interested in the matter. In all Germany, look at the bishops, princes, noblemen, the inhabitants of town and country—how confidently they go on sleeping and snoring in their indifference to the question. They presume to think there is no need for action; the matter will adjust itself; there will always be pastors and preachers. But assuredly they deceive themselves if they think they are consulting their best interests in this affair; for they will, as the text says, become foolish and fail to recognize the will of God. Therefore they will some day have to experience what they do not now believe: in a few years after our day they will seek preachers and find none; they will have to hear rude, illiterate dolts who, lacking understanding of the Word of God, will, like all stupid Papists, preach the vile, offensive things of the Pope, about consecrated water and salt, about gray gowns, new monasteries and the like.
6. Cry, preach and admonish as we will, no one will hear; foreseeing which, Paul prophesies that they who observe not God's will, become unwise, foolish, and consequently waste the day of grace and neglect their salvation. Now, it is God's will we should sanctify his name, love and advance his Word, and so aid in building up his kingdom. When we fulfill his will in these things, he will regard our desires, providing us with daily bread and granting peace and happiness.
