Colossians 2:11-13

In Him you were also circumcised with a circumcision not made with hands, but by the [spiritual] circumcision of Christ in the stripping off of the body of the flesh [the sinful carnal nature], having been buried with Him in baptism and raised with Him [to a new life] through [your] faith in the working of God, [as displayed] when He raised Christ from the dead. When you were dead in your sins and in the uncircumcision of your flesh (worldliness, manner of life), God made you alive together with Christ, having [freely] forgiven us all our sins
