Colossians 212 Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.
In this and the surrounding verses we see the nature of true faith. It is being IN CHRIST “in whom (we) are circumcised with the circumcision made without hands (definitive sanctification),” it is being “buried with him in baptism, wherein also (we) are risen with him through the faith of the operation of God (new life).” Ingrafting into Christ is faith (Heidelberg Catechism Q/A 20,21). Faith is the bond that unites us to Christ, performed by the operation of God at regeneration, that becomes conscious in the believer’s life as he believes the Scriptures and lays hold on Christ as the only hope of salvation.
