In Scripture, the doctrine of redemption is not so heavenly focused it is of no earthly good. All matters in which angels have desired to investigate and learn more (1 Peter 1:12) have daily relevance and practical application to humans.
After instructing his readers on the exalted blessings of God’s abundant grace in Christ and how baptism is the trysting place of heaven’s grace and humanity’s penitent, obedient faith (Romans 6:1-11), Paul states in practical terms how this impacts every flesh-and-blood member of the redeemed: “Therefore do not let sin reign in your mortal body, that you should obey it in its lusts. And do not present your members as instruments of unrighteousness to sin but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God. For sin shall not have dominion over you, for you are not under law but under grace” (Romans 6:12-14).
The reason why you can “Certainly NOT!” continue in sin that grace may abound is because justification by the Redeemer’s blood demands sanctification among the redeemed. Redemption in action means:
Sin is not to reign in your mortal body.
You do not present your members as instruments/weapons of unrighteousness.
You do present your members as instruments/weapons of righteousness.
Sin does not have dominion over you because you are now living under the reign of grace.
Justification means that in the eyes of God you are sinless about the past.
Sanctification means you are to sin less and less and less in the present.
