A person knows they are born again when they have true faith in Christ and repentance from sin.
A person can be assured of their new birth when they express genuine faith in Jesus Christ and demonstrate repentance from sin. According to John 1:12-13, those who receive Christ are given the right to become children of God, not by human decision but born of God. This indicates that true belief is a result of regeneration. Upon being born again, individuals often experience a profound change in their understanding and love for God, which motivates them to trust in Christ for salvation. The presence of these spiritual realities in a person's life is a strong indication that they have indeed been born of God and are now part of His family.
