LIVING IN THE SPIRIT AS GOD'S CHILDREN.

1. This text, like the preceding one, is an exhortation to Christian life and works. The language employed, however, is of different construction. The hateful machinations of the devil, by which he produces so much disaster in the world, make it necessary to urge this exhortation in many different forms upon those who have become Christians. For when God out of grace, without any merit on our part, bestows upon us the forgiveness of sins which we ourselves are unable to buy or acquire, the devil instigates men at once to conclude and exclaim: Oh, in that case we need no longer do good! Whenever, therefore, the apostle speaks of the doctrine of faith, he is obliged continually to maintain that grace implies nothing of that kind. For our sins are not forgiven with the design that we should continue to commit sin, but that we should cease from it. Otherwise it would more justly be called, not forgiveness of sin but permission to sin.

2. It is a shameful perversion of the salutary doctrine of the Gospel and great and damnable ingratitude for the unfathomable grace and salvation received, to be unwilling to do good. For we ought in fact to be impelled by this very grace to do, with all diligence and to the utmost of our knowledge and ability, everything that is good and well-pleasing to God, to the praise and glory of his name.

3. Of this Paul reminds and admonishes us here, in plain and simple but earnest and important words, in which he points out to us how much we owe to God for that which we have received from him, and what injury we shall suffer if we do not value it as we should, and act accordingly. He says:

"We are debtors, not to the flesh, to live after the flesh."

4. Because we have been redeemed from the condemnation we deserved by our sins, and now have eternal life through the Spirit of Christ dwelling in us (he speaks of this in the preceding verses), therefore we are debtors to live after the Spirit and obey God. This Paul declares also in the text for last Sunday: "Now being made free from sin and become servants to God, ye have your fruit unto sanctification." Rom 6, 22. Therefore, he says, ye are debtors; your new calling, station, and nature require of you that, since ye have become Christians and have the Holy Spirit, ye should live as the Holy Spirit directs and teaches. It is not left to your own caprice to do or to leave undone. If ye desire to glory in the possession of grace and the Holy Spirit, ye must confess yourselves debtors to live, not after the flesh, the only desire of which is to continue in sin, but after the Spirit; the Spirit shows you that, having been baptized and redeemed from sin, ye must turn from sin to the new life of righteousness and not from that new life to sin.

"For if ye live after the flesh, ye must die."

5. Here judgment is plainly and tersely pronounced on the pretensions of those foolish people who seek to make the freedom of grace a pretext for giving license to the flesh. The apostle speaks these words that he may deter them from presumption, lest in place of the life and grace in which they pride themselves, they bring upon themselves again eternal wrath and death. It would be utterly inconsistent in you who are now saved and freed from eternal death to desire henceforth to live after the flesh. For if ye do that, ye need not imagine that ye shall retain eternal life; ye will be subject to death and condemned to hell. For ye know that it was solely because of your sins that ye lay under the wrath of God and had incurred death, and that it was because ye lived after the flesh that ye deserved condemnation. Most assuredly Christ has not died for those who are determined to remain in their sins; he has died that he might rescue from their sins those who would gladly be released but cannot liberate themselves.

6. Therefore, let him that is a Christian take care not to be guilty of such nonsense as to say: I am free from the Law, therefore I may do as I please. Rather let him say and do the contrary. Let him, because he is a Christian, fear and shun sin, lest he fall from his freedom into his former state of bondage to sin under the Law and God's wrath; or lest the life, begun in God, lapse again into death. For here stands the express declaration, "If ye live after the flesh, ye must die;" as if the apostle meant: It will not avail you that ye have heard the Gospel, that ye boast of Christ, that ye receive the sacraments, so long as ye do not, through the faith and Holy Spirit received, subdue your sinful lusts, your ungodliness and impiety, your avarice, malice, pride, hatred, envy and the like.

7. For the meaning of "living after the flesh" has been repeatedly stated and is readily understood. It includes not only the gross, sensual lust of fornication or other uncleanness, but everything man has inherited by his natural birth; not only the physical body, but also the soul and all the faculties of our nature, both mental and corporal—our reason, will and senses—which are by nature without the Spirit and are not regulated by God's Word. It includes particularly those things which the reason is not inclined to regard as sin; for instance, living in unbelief, idolatry, contempt of God's Word, presumption and dependence on our own wisdom and strength, our own honor, and the like. Everything of this nature must be shunned by Christians (who have the Holy Spirit and are hence able to judge what is carnal) as a fatal poison which produces death and damnation.
