Epistle Sermons, Vol. 3: Trinity Sunday to Advent

by Martin Luther

13. To be "led by the Spirit of God" means, then, to be given a heart which gladly hears God's Word and believes that in Christ it has grace and the forgiveness of sins; a heart which confesses and proves its faith before the world; a heart which seeks, above all things, the glory of God, and endeavors to live without giving offense, to serve others and to be obedient, patient, pure and chaste, mild and gentle; a heart which, though at times overtaken in a fault and it stumble, soon rises again by repentance, and ceases to sin. All these things the Holy Spirit teaches one if he hears and receives the Word, and does not wilfully resist the Spirit.

14. On the other hand, the devil, who also is a spirit, persuades the hearts of the worldlings. But it soon becomes evident that his work is not that of a good spirit or a divine spirit. For he only leads men to do the reverse of that which the Spirit of God leads them to do; then they find no pleasure in hearing and obeying God's Word, but despise God, and become proud and haughty, avaricious, unmerciful.

15. Let every one therefore take heed that he do not deceive himself. For there are many who claim to be Christians and yet are not. We perceive this from the fact that not all are led by the Spirit of God. Some spirit there must be by which men are led. If it is not the Spirit of God leading them to oppose the flesh, then it must be the other and evil spirit leading them to give way to the flesh and its lusts and to oppose the Spirit of God. They must, therefore, either be God's own, his dear children, his sons and his daughters, called to eternal life and glory; or they must be rejected and abandoned, children of the devil, and with him heirs of eternal fire.

16. Paul takes occasion to speak more at length on the words "sons of God," and proceeds in beautiful and comforting words to describe the nature and glory of this sonship. He only begins the subject, however, in today's text. He says:

"For ye received not the spirit of bondage again unto fear; but ye received the spirit of adoption, whereby we cry, Abba, Father."

17. This is a noble and comforting text, worthy of being written in letters of gold. Because ye now through faith, he means to say, have the Holy Spirit and are led by him, ye are no longer in bondage as ye were when under the Law; ye need no longer be afraid of its terrors and its demands, as if God would condemn and reject you on account of your unworthiness and the remaining infirmity of your flesh. On the contrary, ye have the consolation that, through faith, ye have the assurance of God's grace, and may consider God your Father and call upon him as his children.

TWO KINDS OF PREACHING AND OF WORKS.

18. Thus he contrasts the two kinds of works which spring from the two kinds of preaching and doctrine—of the Law and of the Gospel—and which constitute the difference between the Christians and those still without faith and the knowledge of Christ. They who have nothing and know nothing but the Law, can never attain to true, heartfelt trust and confidence in God, though they do ever so much and exercise themselves ever so earnestly in the Law. For when the Law shines upon them in real clearness and they see what it demands of them and how far they come short of its fulfilment, when it thus discloses to them God's wrath, it produces in them only a terror, a fear and dread, of God under which they must at last perish if they be not rescued by the Gospel. This is what Paul here terms "the spirit of bondage," one that produces only fear and dread of God. But, on the other hand, if the heart grasps the preaching of the Gospel, which declares that, without any merit or worthiness on our part, God forgives us our sins, for Christ's sake, if we believe in him—then it finds in God's grace comfort against the terrors of the Law; then the Holy Spirit enables it to abide in that confidence, to hold fast to that comfort, and to call upon God sincerely in that faith, even though it feels and confesses to be still weak and sinful. This is what is meant by receiving "the spirit of adoption."

19. Paul speaks of the "spirit of bondage" and the "spirit of adoption" according to the customs of his times. In those days men-servants and maid-servants were the property of the master of the house in the same sense that a cow was his property. He bought them with his money; he did with them as he pleased, just as with his cattle. They were afraid of their master and had to expect stripes, imprisonment and punishment even unto death. They could not say, So much of my master's property belongs to me, and he must give it to me. But they had always to reflect: Here I serve for my bread only; I have nothing to expect but stripes, and must be content to have my master cast me out or sell me to someone else whenever he chooses. They could never have a well-grounded hope of release from such fear and bondage and coercion.

20. Such a slavish spirit, such a captive, fearful and uncertain spirit, ye do not have, says the apostle. Ye are not compelled to live continually in fear of wrath and condemnation as are the followers of Moses and all who are under the Law. On the contrary, ye have a delightful, free spirit, one confident and contented, such as a child entertains toward its father, and ye need not fear that God is angry with you or will cast you off and condemn you. For ye have the Spirit of his Son (as he says above and in Galatians 4, 6) in your heart and know that ye shall remain in his house and receive the inheritance, and that ye may comfort yourselves with it and boast of it as being your own.
