When we were baptised in Christ Jesus we were baptised in his death; in other words, when we were baptised we went into the tomb with him and joined him in death, so that as Christ was raised from the dead by the Father’s glory, we too might live a new life.
If in union with Christ we have imitated his death, we shall also imitate him in his resurrection. We must realise that our former selves have been crucified with him to destroy this sinful body and to free us from the slavery of sin. When a Christian dies, of course, he has finished with sin.
But we believe that having died with Christ we shall return to life with him: Christ, as we know, having been raised from the dead will never die again. Death has no power over him any more. When he died, he died, once for all, to sin, so his life now is life with God; and in that way, you too must consider yourselves to be dead to sin but alive for God in Christ Jesus.
