How do we know that the necessity of repentance is true?

The doctrine of repentance is deeply rooted in the teachings of Christ and is often overlooked in modern evangelism. Jesus proclaimed the need for repentance as essential for salvation, stating in Luke 13:3 that 'except ye repent, ye shall all likewise perish.' This demonstrates that true repentance is not merely an act of decision but a work of the Holy Spirit in the believer's heart. It contrasts sharply with the prevalent idea of 'easy-believism', emphasizing that genuine repentance cannot be manufactured by human effort but is instead a divine gift.
