'Sanctification' in the Bible

(I am speaking in human terms because of the weakness of your flesh.) For just as you presented your members [as] slaves to immorality and lawlessness, [leading] to lawlessness, so now present your members [as] slaves to righteousness, [leading] to sanctification.

But now, having been set free from sin and having been enslaved to God, you have your fruit [leading] to sanctification, and its end [is] eternal life.
