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.
4. Therefore we are—rather, "were" (it being a past act, completed at once).
buried with him, by baptism into death—(The comma we have placed after "him" will show what the sense is. It is not, "By baptism we are buried with Him into death," which makes no sense at all; but, "By baptism with Him into death we are buried with Him"; in other words, "By the same baptism which publicly enters us into His death, we are made partakers of His burial also"). To leave a dead body unburied is represented, alike in heathen authors as in Scripture, as the greatest indignity (Re 11:8, 9). It was fitting, therefore, that Christ, after "dying for our sins according to the Scriptures," should "descend into the lower parts of the earth" (Eph 4:9). As this was the last and lowest step of His humiliation, so it was the honorable dissolution of His last link of connection with that life which He laid down for us; and we, in being "buried with Him by our baptism into His death," have by this public act severed our last link of connection with that whole sinful condition and life which Christ brought to an end in His death.
that like as Christ was raised from the dead by the glory of the Father—that is, by such a forth-putting of the Father's power as was the effulgence of His whole glory.
even so we also—as risen to a new life with Him.
should walk in newness of life—But what is that "newness?" Surely if our old life, now dead and buried with Christ, was wholly sinful, the new, to which we rise with the risen Saviour, must be altogether a holy life; so that every time we go back to "those things whereof we are now ashamed" (Ro 6:21), we belie our resurrection with Christ to newness of life, and "forget that we have been purged from our old sins" (2Pe 1:9). (Whether the mode of baptism by immersion be alluded to in this verse, as a kind of symbolical burial and resurrection, does not seem to us of much consequence. Many interpreters think it is, and it may be so. But as it is not clear that baptism in apostolic times was exclusively by immersion [see on Ac 2:41], so sprinkling and washing are indifferently used in the New Testament to express the cleansing efficacy of the blood of Jesus. And just as the woman with the issue of blood got virtue out of Christ by simply touching Him, so the essence of baptism seems to lie in the simple contact of the element with the body, symbolizing living contact with Christ crucified; the mode and extent of suffusion being indifferent and variable with climate and circumstances).
