Romans 7:23-25—But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. O wretched man that I am! who shall deliver me from the body of this death? I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
Paul has described the knowledge of the Law causing us to be even more sinful. Once we know the will of God, we discover we cannot help going against it. Our mind desires to do good, but the sin that lives in us has mastered us. We set out to do good and find ourselves doing evil. He saw his life as a prisoner of sin that worked in him. Remember, the Apostle grew up as a Pharisee. He loved the Law. He memorized it and the rules around it. But he was honest enough to know that he was constantly not living up to its high demands. This creates guilt. The guilt makes us miserable. We realize we cannot do what we want no matter how hard we try. In desperation, he asks if there is someone who can deliver him from this vicious cycle. Thank God there is Someone! Jesus Christ our Master! Then he summarized his old condition. My mind is a slave to God’s good law, but that nature that reigned in me was a slave to the evil law of sin. Jesus sets me free from that terrible agonizing conflict. When He becomes Lord, He reigns in my members as I offer them for His service. The entire chapter that follows describes this new life, set free from the control of sin. 8:2 says that through Christ Jesus the law of the Spirit of life set me free from the law of sin and death. The conflict of chapter 7 is often quoted as if it should be our normal experience. NO! We are to be set free by letting Christ be the Master of our bodies and (as we saw in chapter 6) we should become instruments of righteousness.
