'Sanctification' in the Bible

I am speaking in simple terms because of the frailty of your human nature. Just as you once offered the parts of your body as slaves to impurity and to greater and greater disobedience, so now, in the same way, you must offer the parts of your body as slaves to righteousness that leads to sanctification.

But now that you have been freed from sin and have become God's slaves, the benefit you reap is sanctification, and the result is eternal life.
