Romans 6:20 When you were slaves of sin, you were free in regard to righteousness. 21 But what fruit were you getting at that time from the things of which you are now ashamed? The end of those things is death. 22 But now that you have been set free from sin and have become slaves of God, the fruit you get leads to sanctification and its end, eternal life. 23 For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
The Apostle takes us on memory lane. Think about when you were slaves of sin. Did that life lead to lasting satisfaction or to lasting shame? Slavery to sin leads to death of relationships, emotions, physical body and eternal torment if a person never repented of his sin and believed the gospel. For the believer, slavery to sin is an option, but a poor option since it does lead to death of relationships, emotions and physical body. Sin is pleasurable for a short time, but is destructive in the long run.
As believers in Christ, we need to remember we are no longer slaves to sin and live as slaves to God. We are free when we live as slaves to God (John 8:31, 32, 36). Obedience to the Lord Jesus Christ yields good fruit (Galatians 5:22-23). The fruit of being a slave to God leads to sanctification which means being restored to how we were originally created to be. It also leads to eternal life.
Remember the two facts of verse 23. The wages of sin is death. The gift of God is eternal life in Christ Jesus our Lord. Eternal life begins upon belief in the gospel with the promise of having now every spiritual blessing in the heavenlies. Eternal life is consummated in an eternity with God, enjoying the new heavens and earth free from the presence of sin.
Do an inventory of when you, as a believer, were most fulfilled. Is it when you were practicing sin or when you were living the truth of the Word of God? As for me, there is no way I want to live as slave to sin! I hope you believe the same way.
