Romans 6:18-19

And now you celebrate your freedom from your former master—sin. You’ve left its bondage, and now God’s perfect righteousness holds power over you as his loving servants. I’ve used the familiar terms of a “servant” and a “master” to compensate for your weakness to understand. For just as you surrendered your bodies and souls to impurity and lawlessness, which only brought more lawlessness into your lives, so now surrender yourselves as servants of righteousness, which brings you deeper into true holiness.
