The starting point of sanctification is the filthiness, corruption, or stain of sin.
The will of God is eternal because He does not begin to will what He did not will before, nor cease to will what He willed before.
This subsistence, or manner of being of God is his one essence so far as it has personal properties.
Sanctification is the real change in man from the sordidness of sin to the purity of God's image.
The relative property of the Son is to be begotten, that is, so to proceed from the Father as to be a participant of the same essence and perfectly carry on the Father's nature.
Although the whole man partakes of this grace, it is first and most appropriately in the soul and later progresses to the body, inasmuch as the body of the man is capable of the same obedience to the will of God as the soul.
