14. We present a higher doctrine—the Gospel. The Gospel teaches first how sin in ourselves is, through Christ, slain and buried. Thus we obtain a good conscience, a conscience hating and opposing sin, and become obedient to another power. Being delivered from sin we would serve God and exert ourselves to do his pleasure, even though no fear, punishment, judge or executioner existed.
With this point accepted—with the settlement of this minor subject of controversy as to how we are delivered from sin and attain to truly good works, we unite once more on the fundamental principle that good is to be done and evil avoided. Therefore, we immediately conclude: Since we are free from sin and converted to God, we must in obedience to him do good and live no more in sin.
15. Thus does Paul make use of the Law, and of human reason so far as it is able to interpret the Law, to resist them who speak falsely and pervert the right doctrine. Evidently, then, the doctrine of the Gospel does not oppose the doctrine of good works, but transcends it. For it reveals the source and inspiration of good works—not human reason, not human ability, but the grace and power of the Holy Spirit. Now Paul deduces the point:
"For as ye presented [yielded] your members as servants to uncleanness and to iniquity unto iniquity, even so now present [yield] your members as servants to righteousness unto sanctification [holiness]."
