'Sanctification of the Spirit' in the Bible

But we are bound to give thanks always to God for you, brethren, beloved by the Lord, because God hath from the beginning chosen you to salvation, through sanctification of the Spirit, and belief of the truth:

Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, to obedience and sprinkling of the blood of Jesus Christ: Grace to you, and peace, be multiplied.
