Romans 8:9-11—But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness. But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
The Apostle saw things in black and white. He declared that every man and woman is controlled by the sinful nature or by the Spirit. The Spirit of God cannot live in someone without controlling him or her. Most Christians seem to think that the Spirit lives in them but they are often controlled by their sinful nature. That isn’t the teaching we find here. Paul is telling us that if the Spirit of God lives in us, that old nature is dead to us, and our spirit is alive because of the righteousness of Christ. In 6:11 he encouraged us to consider ourselves dead to sin but alive to God. Yet, most Christians consider themselves alive to sin and barely alive to God. We have compromised the Word and the power of the resurrection. It is not that we must insist that we have become sinless, but that we must recognize the power of the resurrection to break the control of sin and replace it with the control of the Spirit. Because of this common misconception, we tend to read verse 11 as something that will happen when we are physically resurrected one day off in the future. He is speaking of this very moment. The power of the Spirit that raised Jesus is at work in you, this very moment, to give life. Throughout the New Testament, death is walking in sin, and life is being in the Spirit of God. This physical house of our bodies can be made alive to obey the Spirit of Life, the Spirit of Christ, who indwells us. If Christ lives in you, consider yourself awakened to life, empowered to walk in holiness, and controlled by the Spirit of God. Remember: Know that you are enabled by the power that raised Jesus to walk in newness of life.
