How do we know that the dominion of sin is broken for believers?

The breaking of sin’s dominion over a believer’s life is grounded in the Gospel. Romans 6:14 states, 'For sin shall not have dominion over you, for you are not under law but under grace.' This signifies that, while believers will still struggle with sin, they are not ultimately enslaved to it. The power of sin is defeated through Christ's sacrificial death, which has paid the penalty for sin and has secured a new relationship with God, enabling believers to live righteously through the assistance of the Holy Spirit.
