In the first four chapters of Romans, we understand the Gospel, how to become a Christian through faith in Christ Jesus. In chapters five through seven we understand our identity as Christians. Romans chapter eight describes the blessed security we have in being a Christian. In Romans 7:21-24, the Apostle Paul describes the law of sin as the evil in human nature that seeks to destroy us. He introduces the law of God which delivers the Christian from the law of sin and death. A Christian is "in Christ Jesus." Paul uses this prepositional phrase over 160 times in his epistle. When a person believes in Christ Jesus, our Savior enters into him (John 14:23-28). More importantly, the believer is "in Christ." His life is totally immersed in his Savior's. The law of the Spirit of life in Christ Jesus conquers the law of sin and death. The Holy Spirit is mentioned eighteen times in chapter eight of Romans.
