How do we know if we are truly born again?

The question of whether one is truly born again is critically important in the Christian faith. In John 3:3, Jesus states, 'Except a man be born again, he cannot see the kingdom of God.' This new birth involves a significant transformation, which is evidenced by a changed life marked by faith in Christ, a desire to follow God, and fruits of the Spirit as seen in 2 Peter 1:5-8. It's essential for believers to evaluate their faith not merely by external religious practices but by the internal witness of the Holy Spirit and the resulting changes in their lives that reflect the love and lordship of Christ.
