7 For he who has died has been freed from sin.
Paul writes in his letter to the Romans in chapter 6, verse 7 that the one who has died has been freed from sin. We understand from Luke 1:77 that being freed from sin—that is, the forgiveness of sin—is equivalent to receiving salvation from God through Jesus Christ. Therefore, we must understand and teach others the manner in which they must die in order to be freed from sin, as this act will bring about the salvation of their souls. The answer to the way in which we die to sin is given in Romans 6.
After explaining to these Christians that grace abounded much more through Christ where sin abounded (Rom. 5:20–21), Paul poses the following question: “Shall we continue in sin that grace may abound?” (Rom. 6:1) He then responds in verses 2 and 3: “2 Certainly not! How shall we who died to sin live any longer in it? 3 Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death?” (Rom. 6:2–3) What we observe in these verses is that the death we must experience is a death to sin, and once we die to sin, we must no longer live in it. Additionally, this death is realized in baptism and is related to the death of Christ. Paul is telling the Christians that their baptism into Christ, which was a baptism into his death, was the way in which they died to sin. Notice verses 4–6:
4 Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life. 5 For if we have been united together in the likeness of His death, certainly we also shall be in the likeness of His resurrection, 6 knowing this, that our old man was crucified with Him that the body of sin might be done away with, that we should no longer be slaves of sin.
Baptism—an act of immersion into water—unites us with Christ in his death, burial, and resurrection, and the purpose of it is so “that the body of sin might be done away with that we should no longer be slaves to sin,” but rather “should walk in newness of life.” This operation is only possible by the glory of the Father that raised Christ from the dead. Now, we arrive back at verse 7, where Paul says, “for”—that is, because—“he who has died has been freed from sin.” Clearly Paul has connected baptism with forgiveness of sin, which in turn, is the gift of salvation. In baptism and by the grace of God, we are saved from our sins, and we never die again. However, just as Christ, we must live to God, not giving ourselves over to sin once again, but rather allowing ourselves to be his instruments of righteousness (vv. 8–12). This lifestyle is accomplished only after we have submitted ourselves to Christ’s commandment of becoming his disciples through baptism for the forgiveness of sins (Matt. 28:18–20; Mark 16:16; Acts 2:38).
