(15-23) Free forgiveness! What does that mean? Freedom to sin? Far from it. That were to return into the old slavery. To yield to sin is to be the servant or slave of sin with its consequence — death. On the other hand, obedience and righteousness go together. Happily you have escaped from sin, and taken service with righteousness. Service, I say, using a plain human figure to suit your imperfect and carnal apprehension of spiritual things. Exchange the service of uncleanness for that of righteousness. I appeal to your own experience. You found that sin brought you no pay from your master but death. Now you are started upon a road that leads to sanctification and eternal life. This will be given you, not as wages, but as the free gift of God in Christ.
Romans 6:15-23
15 What then? shall we sin, because we are not under the law, but under grace? God forbid.
16 Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
17 But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine whichc was delivered you.
18 Being then made free from sin, ye became the servants of righteousness.
19 I speak after the manner of men because of the infirmity of your flesh: for as ye have yielded your members servants to uncleanness and to iniquity unto iniquity; even so now yield your members servants to righteousness unto holiness.
20 For when ye were the servants of sin, ye were free from righteousness.
21 What fruit had ye then in those things whereof ye are now ashamed? for the end of those things is death.
22 But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life.
23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
