“What then? Shall we sin because we are not under law but under grace? May it never be! Do you not know that when you present yourselves to someone as slaves for obedience, you are slaves of the one whom you obey, either of sin resulting in death, or of obedience resulting in righteousness?” (Romans 6:15-16).
Freedom from sin does not mean freedom to sin.
From Paul’s day until now, the gospel of grace has been accused of providing license to sin. If salvation is the gift of God’s grace, legalists argue, wholly apart from human works, what will motivate people to lead holy lives? In the face of such opposition, Paul never gave an inch on the vital issue of salvation by grace—and neither can we. The Bible teaches a salvation that is entirely by God’s free grace through faith and in which human works play no part.
But there is a second way in which the doctrine of salvation by grace may be perverted. Fulfilling the legalists’ fears, some believe that since God’s grace covers all their sins, they can live as they choose. In today’s passage Paul addresses that error.
The very thought of a Christian living in persistent, habitual sin horrified Paul. To the hypothetical question “Shall we sin because we are not under law but under grace?” Paul responded emphatically, “May it never be!” As in verse 2, the apostle used the strongest form of negation in the Greek language. In our English vernacular, Paul was saying “Ridiculous! Impossible! No way!” He went on to point out the self-evident truth that no one can serve two masters. Everyone is either a servant of sin or a servant of God; there is no third option. And the one to whom people habitually yield their obedience is their real master, no matter what they may claim.
Don’t be deceived by those who claim that since Christians are forgiven, they can therefore sin at will. Such people know nothing of God’s grace, which, far from giving us license to sin, “instruct[s] us to deny ungodliness and worldly desires and to live sensibly, righteously and godly in the present age” (Titus 2:12).
