How does the New Covenant affect the way we view sin?

Under the New Covenant, believers receive a new heart that recognizes the pervasive nature of sin in their lives. This understanding is encapsulated in Romans 7:18, where Paul reflects on the law of sin that dwells within him. The New Covenant not only reveals our sinful nature but also emphasizes that our standing before God is based on Christ's righteousness alone, not our works. Therefore, Christians are encouraged to rest not in their personal efforts, but in the finished work of Christ, which grants them forgiveness and new life.
