How does circumcision relate to repentance?

Circumcision, particularly when viewed through the lens of the New Testament, serves as a symbol of repentance. Just as physical circumcision was a painful process, so too is the act of repentance, which often requires a heartfelt acknowledgment of sin and a turning away from it. Colossians 2:11 emphasizes that true circumcision is a work done by Christ that cuts away the sins of the flesh. This metaphor highlights that repentance is not merely feeling sorry for sin but involves a radical change of heart prompted by the Holy Spirit, enabling believers to turn to Christ in faith.
