How do we know Christ's power to save is true?

We can trust in Christ's power to save because it is firmly established in Scripture. Romans 5:6-10 asserts that Christ, in His love, died for the ungodly, confirming His authority to redeem even the most wretched sinner. This is further corroborated by personal testimonies, such as that of the Apostle Paul, who experienced transformation from a persecutor of Christians to a devoted follower of Christ. The consistency of biblical teaching about Jesus' redemptive work reassures believers that His promise holds true, providing a firm foundation for our faith in His saving grace.
