What does it mean to be saved from the power of sin?

When one is saved, they are liberated from the dominion of sin, gaining a new nature that seeks to follow Christ. Ephesians 2:1 states that we were dead in our sins, but through Christ, we receive a new heart and life that empowers us to live for Him. This transformation means we are no longer under the control of Satan, and we can respond to the gospel with faith and repentance. Salvation involves not only justification but also sanctification, where believers are progressively conformed to the image of Christ and learn to walk in obedience.
