How do we know that grace reigns in the lives of believers?

Romans 5:21 states that grace reigns through righteousness leading to eternal life by Jesus Christ our Lord. This signifies that even though sin brought about death, grace is far greater and dominates in the hearts of those who are justified by faith. This is a profound truth for believers, as it highlights that salvation is not based on our merit but on Christ's righteousness. By receiving grace, believers experience transformation and assurance of eternal life. Thus, grace does not simply cover sin; it reigns and empowers us to live in a manner that honors God.
