11 In Him you were also circumcised with the circumcision made without hands, by putting off the body of the sins of the flesh, by the circumcision of Christ, 12 buried with Him in baptism, in which you also were raised with Him through faith in the working of God, who raised Him from the dead. 13 And you, being dead in your trespasses and the uncircumcision of your flesh, He has made alive together with Him, having forgiven you all trespasses (Colossians 2:11–13, NKJV)
The apostle of Christ treats physical circumcision as wholly inferior to “the circumcision of Christ,” which takes place when the sinner is “buried with Christ in baptism.” Cutting off the foreskin of flesh was but a figure of what really happens in the circumcision of Christ – a cutting off of sins performed by divine hands. God performs a spiritual operation when the sinner is baptized; He cuts away the sinner’s sins and gives newness of life (Rom. 6:4). It is indisputable that the circumcision of Christ (the cutting away of sin) takes place when the sinner is buried with Christ in baptism (v. 12). The result is forgiveness of sins (v. 13). This spiritual circumcision is real; as real as the sinner upon whom the operation is performed. Without this operation of God the sinner remains dead in sin. With it, he or she is forgiven and alive with Christ.
