What does repentance mean in the context of salvation?

In the context of salvation, repentance involves a radical change of mind and heart regarding sin and self-reliance. It is an acknowledgment that one cannot achieve righteousness by their own efforts, leading them to rely solely on Jesus Christ for salvation. This is beautifully illustrated in the story of the Philippian jailer, who, after being awakened to his sinful state, repented by turning from his former life as a jailer inflicting stripes to serving Paul and Silas by washing their wounds. Acts 16:33-34 depicts this transformation, where he not only physically cares for them but also publicly declares his faith in Christ through baptism, demonstrating his complete renouncement of his former ways. True repentance results in a life reoriented towards serving Christ and living in His grace.
