Paul concludes chapter 6 with many powerful truths. Before believers were saved, they were free from righteousness. They were not able to produce works or fruit worthy of repentance, i.e. save ourselves (verse 20.) Verse 22 shows the corollary. Believers are now free from sin, are servants of God, have fruit unto holiness, and the end everlasting life. As the end of believers is everlasting life, their actions or lack thereof cannot "unsave" them. Verse 23 mentions the wages of sin are death; the soul that sins shall die. Wages are a just payment; however, the gift of God, no payment on the part of the receiver, is eternal life.
