6:3 {3} Know ye not, that so many of us as were baptized into {c} Jesus Christ were baptized into his death?
(3) There are three parts of this sanctification: that is, the death of the old man or sin, his burial, and the resurrection of the new man, descending into us from the virtue of the death, burial, and resurrection of Christ, of which benefit our baptism is a sign and pledge.
(c) To the end that growing up as one with him, we should receive his strength to extinguish sin in us, and to make us new men.
6:3 So many of us as were baptized into Jesus Christ, etc. The fact that every follower of Christ has died to sin is shown by his baptism. All its symbolism points to death. To be baptized into Christ means to enter into a vital union with him, so as to be found in him. See Ga 3:27.
Were baptized into his death. But this baptism into Christ implies death, for it is a baptism into the death of Christ. That the subjects of baptism are partakers of his death is shown by the form of baptism. It is a burial.
6:3 As many as have been baptized into Jesus Christ have been baptized into his death - In baptism we, through faith, are ingrafted into Christ; and we draw new spiritual life from this new root, through his Spirit, who fashions us like unto him, and particularly with regard to his death and resurrection.
6:3-10 Baptism teaches the necessity of dying to sin, and being as it were buried from all ungodly and unholy pursuits, and of rising to walk with God in newness of life. Unholy professors may have had the outward sign of a death unto sin, and a new birth unto righteousness, but they never passed from the family of Satan to that of God. The corrupt nature, called the old man, because derived from our first father Adam, is crucified with Christ, in every true believer, by the grace derived from the cross. It is weakened and in a dying state, though it yet struggles for life, and even for victory. But the whole body of sin, whatever is not according to the holy law of God, must be done away, so that the believer may no more be the slave of sin, but live to God, and find happiness in his service.
