Why is understanding circumcision made without hands important for Christians?

The concept of circumcision made without hands refers to the spiritual work that Christ accomplishes in the hearts of His people, as stated in Colossians 2:11. This signifies that believers have been transformed by God's grace through Christ's atoning work, rather than by any works of their own. Physical circumcision in the Old Testament was a shadow of this deeper spiritual reality. Understanding this distinction helps Christians realize that their acceptance before God relies solely on Christ's righteousness and not on their obedience, fostering humility and dependence on God's grace.
