The Westminster Shorter Catechism defines a Christian’s sanctification as the work of God's free grace, whereby we are renewed in the whole man after the image of God, and are enabled more and more to die unto sin, and live unto righteousness. **See - Ezek. 36:27; Phil 2:13; 2 Thess. 2:13; 2 Cor. 5:17; Eph. 4:23-24; 1 Thess. 5:23; Rom. 6; 2Cor 7:1; 1 Pet. 2:24.
This is a tremendously encouraging teaching of Scripture that is born of regeneration and justification, is empowered presently by the Spirit, and is promised completion for all who are in Christ. All this finds its beginning and fulfillment in through our union with Jesus Christ and Christ alone.
As you seek to understand this teaching from the scriptures, it is helpful to know that other hungry and thirsty ones have sought to understand their sanctification and have given important writings to the church to help and encourage us as well. Please consider one of these wonderful resources as you seek to understand the Lord’s work in making you more into the image of Christ.

He is our sanctification.
