What does Romans 8:2 mean?
Paul wrote in the previous verse that there is absolutely no condemnation for those who are in Christ Jesus. This verse begins to describe why that is true, and it has much to do with the Holy Spirit. This is only the second mention of the Holy Spirit in Romans, but merely the first of about 19 mentions of the Spirit in chapter 8!Why is there no condemnation from God for those in Christ Jesus? The law—or principle—of the Spirit of life has set us free in Christ Jesus from the law—or principle—of sin and death. The word used twice as "law" in this verse does not refer to the law of Moses, about which Paul has written so much in Romans. Instead, it describes the idea of a universal truth.
The first truth or principle is the Spirit of life. Put another way, the Spirit of God always gives or brings life. That notion has set Christians free only in Christ Jesus. Without faith in Christ, we will not be justified by God (Romans 5:1), and if we are not justified we will not receive the Spirit who brings life. Put positively, because we have faith in Christ, God has given to us His Spirit that brings life. That has set us free from the law or principle of sin and death.
That second law is just that sin always, always leads to death. It is the reason we were all condemned to eternal death and separation from God in the first place (Romans 3:23; 6:23). The only way to escape from the law of sin and death is to access the law of the Spirit of life through faith in Christ.
