Romans 6:16-18

New Catholic Bible

¹⁶ Do you not know that if you offer yourself as an obedient slave, you are the slave of the one you obey—either of sin, which leads to death, or of obedience, which leads to righteousness?

¹⁷ Once you were slaves of sin, but, thanks be to God, you have become obedient in your heart to that pattern of teaching to which you have been delivered. ¹⁸ Now, having been set free from sin, you have become slaves of righteousness.
