Romans 6 focuses on how Christians live their lives. The central message in this chapter is that believers are dead to sin and alive in Christ. Paul argues that sin no longer has power over Christians because they have been freed from it by their faith in Jesus. He also emphasizes the importance of living in a way that honors God instead of living for the pleasures of the flesh. Overall, Romans 6 encourages Christians to live in freedom and obedience to Christ's teachings, and to use their bodies and lives as instruments of righteousness.
