Why is repentance a necessary aspect of salvation?

Repentance plays a crucial role in the process of salvation, as it demonstrates an acknowledgment of one’s sinful state and a sincere desire to turn away from it towards God. Acts 2:38 states, 'Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins,' which signifies that repentance is tied to the forgiveness of sins. It crucially expresses a transformed heart, not merely a change in behavior. This aligns with what Jesus teaches in Luke 13:3, where He states, 'except ye repent, ye shall all likewise perish,' emphasizing that repentance is not an option but a necessary evidence of true faith and turning to Christ.
