Romans 8:13

For if ye live after the flesh, ye shall die--in the sense of Rom 6:21. but if ye through the Spirit do mortify the deeds of the body--(See on Rom 7:23). ye shall live--in the sense of Rom 6:22. The apostle is not satisfied with assuring them that they are under no obligations to the flesh, to hearken to its suggestions, without reminding them where it will end if they do; and he uses the word "mortify" (put to death) as a kind of play upon the word "die" just before. "If ye do not kill sin, it will kill you." But he tempers this by the bright alternative, that if they do, through the Spirit, mortify the deeds of the body, such a course will infallibly terminate in "life" everlasting. And this leads the apostle into a new line of thought, opening into his final subject, the "glory" awaiting the justified believer. Note, (1) "There can be no safety, no holiness, no happiness, to those who are out of Christ: No "safety," because all such are under the condemnation of the law (Rom 8:1); no holiness, because such only as are united to Christ have the spirit of Christ (Rom 8:9); no happiness, because to be "carnally minded is death" (Rom 8:6)" [HODGE]. (2) The sanctification of believers, as it has its whole foundation in the atoning death, so it has its living spring in the indwelling of the Spirit of Christ (Rom 8:2-4). (3) "The bent of the thoughts, affections, and pursuits, is the only decisive test of character (Rom 8:5)" [HODGE]. (4) No human refinement of the carnal mind will make it spiritual, or compensate for the absence of spirituality. "Flesh" and "spirit" are essentially and unchangeably opposed; nor can the carnal mind, as such, be brought into real subjection to the law of God (Rom 8:5-7). Hence (5) the estrangement of God and the sinner is mutual. For as the…

The apostle, having fully explained the doctrine of justification, and pressed the necessity of sanctification, in this chapter applies himself to the consolation of the Lord's people. Ministers are helpers of the joy of the saints. "Comfort ye, comfort ye my people," so runs our commission, Isa 40:1. It is the will of God that his people should be a comforted people. And we have here such a draught of the gospel charter, such a display of the unspeakable privileges of true believers, as may furnish us with abundant matter for joy and peace in believing, that by all these immutable things, in which it is impossible for God to lie, we might have strong consolation. Many of the people of God have, accordingly, found this chapter a well-spring of comfort to their souls, living and dying, and have sucked and been satisfied from these breasts of consolation, and with joy drawn water out of these wells of salvation. There are three things in this chapter: I. The particular instances of Christians' privileges (v. 1-28). II. The ground thereof laid in predestination (Rom 8:29, Rom 8:30). III. The apostle's triumph herein, in the name of all the saints (Rom 8:31 to the end).

8:13 you will die: Death is the consequence of sin. Those who consistently yield to sin will suffer spiritual death (eternal condemnation). The presence of the Holy Spirit in the lives of believers makes it possible for them to turn away from sin. The result is eternal life (you will live).
