“Whom He did foreknow, He also did predestinate to be conformed to the image of His Son.” Romans 8:29.
Here is the glorious pattern of a child of God. Sanctification is a conformity to the image and the example of Christ. The more the believer is growing like Jesus, the more he is growing in holiness. And, on the contrary, the less resemblance there is to Christ in his principles, in the habit of his mind, in his spirit, temper, daily walk, yes, in every action and in every look, the less is he advancing in the great work of holiness.
