“We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead … we too might walk in newness of life” (v4). Paul didn’t want the believers in Rome to think that receiving God’s grace meant that they had permission to keep living in sinful ways. The whole point of salvation, symbolized in baptism, is that we are “dead” to our old sinful life and, by the power of Christ’s resurrection, are reborn to live according to His righteousness.
“For one who has died has been set free from sin” (v7). God’s grace washes us clean and breaks the power of sin over us, so that we can live for Him.
