Romans 6:18-20

New Revised Standard Version Catholic Edition

¹⁸ and that you, having been set free from sin, have become slaves of righteousness. ¹⁹ I am speaking in human terms because of your natural limitations.^[a] For just as you once presented your members as slaves to impurity and to greater and greater iniquity, so now present your members as slaves to righteousness for sanctification.

²⁰ When you were slaves of sin, you were free in regard to righteousness.
