Romans 6:12-22 New King James Version (NKJV)
12 Therefore do not let sin reign in your mortal body, that you should obey it in its lusts. 13 And do not present your members as [a]instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God. 14 For sin shall not have dominion over you, for you are not under law but under grace.
From Slaves of Sin to Slaves of God
15 What then? Shall we sin because we are not under law but under grace? Certainly not! 16 Do you not know that to whom you present yourselves slaves to obey, you are that one’s slaves whom you obey, whether of sin leading to death, or of obedience leading to righteousness? 17 But God be thanked that though you were slaves of sin, yet you obeyed from the heart that form of doctrine to which you were [b]delivered. 18 And having been set free from sin, you became slaves of righteousness. 19 I speak in human terms because of the weakness of your flesh. For just as you presented your members as slaves of uncleanness, and of lawlessness leading to more lawlessness, so now present your members as slaves of righteousness [c]for holiness.
20 For when you were slaves of sin, you were free in regard to righteousness. 21 What fruit did you have then in the things of which you are now ashamed? For the end of those things is death. 22 But now having been set free from sin, and having become slaves of God, you have your fruit [d]to holiness, and the end, everlasting life.
