'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.

It is because of God that you are in union with the Messiah Jesus, who for us has become wisdom from God, as well as our righteousness, sanctification, and redemption.

At all times we are obligated to thank God for you, brothers who are loved by the Lord, because God chose you to be the first fruits for salvation through sanctification by the Spirit and through faith in the truth.
