What shall we say, then? Should we continue to live in sin so that God’s grace will increase? 2Certainly not! We have died to sin—how then can we go on living in it? 3For surely you know that when we were baptized into union with Christ Jesus, we were baptized into union with his death. 4By our baptism, then, we were buried with him and shared his death, in order that, just as Christ was raised from death by the glorious power of the Father, so also we might live a new life. 5For since we have become one with him in dying as he did, in the same way we shall be one with him by being raised to life as he was. 6And we know that our old being has been put to death with Christ on his cross, in order that the power of the sinful self might be destroyed, so that we should no longer be the slaves of sin. 7For when people die, they are set free from the power of sin. 8Since we have died with Christ, we believe that we will also live with him. 9For we know that Christ has been raised from death and will never die again—death will no longer rule over him. 10And so, because he died, sin has no power over him; and now he lives his life in fellowship with God. 11In the same way you are to think of yourselves as dead, so far as sin is concerned, but living in fellowship with God through Christ Jesus.
As Paul ends chapter 5; boasting about God's grace in forgiving sins apart from the law. Should we then act as if morality doesn't matter? No, but we should invite the Holy Spirit to help us to live without sin - because our hearts and lives are transformed by God's love and presence.
Sin has no power over me. I live my life in fellowship with you O Lord.
