'Free from Sin' in the Bible

For this we know, that our old self was crucified with Christ, in order that the slave of sin might be destroyed; so that we should no longer be in slavery to sin??7 for he who is dead is set free from sin.

and being set free from sin, you became the slaves of righteousness??19 I speak in these homely figures because of the weakness of your fleshly nature??ust as you once surrendered your faculties into slavery to impurity and to all lawlessness, so now you must surrender your faculties into slavery to righteousness, unto deeds of holiness.

But now that you have been set free from sin and become slaves of God, the harvest-fruit which you are reaping tends to produce holiness, and it ends is life eternal.
