You, however, are controlled not by the sinful nature but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ. But if Christ is in you, your body is dead because of sin, yet your spirit is alive because of righteousness. And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies through his Spirit, who lives in you. Therefore, brothers, we have an obligation—but it is not to the sinful nature, to live according to it. For if you live according to the sinful nature, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live, because those who are led by the Spirit of God are sons of God. (Rom.8:9-14)

As we continue dissecting Romans 8, it is clear that the Holy Spirit is essential for living up to the calling that we have received in Jesus. Paul makes a bold statement when he says, “You, however, are controlled not by the sinful nature but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ” (Rom.8:9). I believe that Paul’s statement here speaks to the potential of the Spirit controlling believers because he has just said in Romans 7 that the flesh wars against the Spirit and he says in other places in Romans that we must choose to serve the Spirit rather than the flesh – it is not automatic because our free will is always in play. But our goal should be complete surrender to the leading of the Spirit.

Interestingly, Paul lifts up the Spirit within us as the mark of belonging to Jesus even more than moral living, Bible knowledge, church attendance or correct doctrines. All of those things are important but the one thing that sets a believer apart from all other people in the world is the Spirit of Christ living in us. Since the Spirit living in us is the great divide among the saved and the unsaved there should also be evidence of the Spirit within us. Paul warns us not to quench the Spirit (I Thess.5:19) or grieve the Spirit (Eph.4:30), but rather instructs us to be filled with the Spirit (Eph.5:18). The fruit of the Spirit (character) and the power of the Spirit (spiritual gifts) are the primary evidences of his presence and should increase as we mature in Christ and mark us as being different from all other people on the planet.

In this section of Romans 8, it is clear that the idea of Christ living in us and the Spirit living in us are the same. Christ lives in us through his Spirit so as we are led by the Spirit we are led by Christ. As we honor the Spirit we honor Christ. As we hear the Spirit we hear Christ.   The Spirit within us is also the Spirit of the Living God whose ultimate purpose for us is the resurrection of the body and eternal life with the Him as our Father. The Spirit that raised Jesus from the dead will do the same for us and fit us with bodies suited for eternity and for the presence of God. In our glorified bodies there will be no fallen or sinful nature. We will have no rebellious impulse that pushes back against the Father’s will. We will carry no shame, no fear, and no sense of condemnation. We will be fully alive in an atmosphere of peace, joy, and love.

In view of that hope, Paul counsels us to put to death the misdeeds of the flesh by the power of the Spirit. He would say to us, “Ignore the impulses of the flesh. Be clear that you have no obligation to honor its demands. It leads to death rather than life – not just in the world to come but in this world as well.” We all reap what we sow. If we give into the impulses and demands of the sinful nature, disaster and destruction will follow at some point. But if we surrender our hearts, our thoughts, and our actions to the Spirit there will be a harvest of life-giving outcomes.” Paul would also tell us that the true sons and daughters of God are marked by evidence of the Spirit in their lives. They are marked by goodness and life. Both the fruit of the Spirit and his power mark them. The more Spirit-led we are, the more power he is willing to entrust to us.

We are all interested in the return on our investments. We wonder what the payoff will be for our time and effort. Many of us watch interest rates and the stock market daily to see what’s happening to our investments because we are investing for the future. Paul’s counsel is to be even more concerned about our spiritual investments because there will be an inescapable payoff some day for good or for pain. The sure investment is always to lay up treasure in heaven and our sensitivity and surrender to the Spirit will be directly proportional to our deposits there. To be all that God wants us to be we must pursue the Spirit of God and all that he offers because what he offers has already been purchased by the blood of the Son.
