A Body of Practical Divinity

2. Sanctification is an intrinsical thing; it lies chiefly in the heart. It is called the adorning the hidden man of the heart, 1 Pet. 3.4. The Dew wets the Leaf, the Sap is hid in the Root; the Religion of some consists only in externals, but Sanctification is deeply rooted in the Soul, Psal. 51.6. In the hidden part thou shalt make me to know wisdom.

3. Sanctification is an extensive thing; it spreads into the whole Man: 1 Thess. 5.23. The God of peace sanctify you wholly. As Original Corruption hath depraved all the Faculties, the whole head is sick, the whole heart faint, no Part sound, as if the whole mass of blood were corrupted; so Sanctification goes over the whole Soul. After the Fall there was Ignorance in the Mind, now in Sanctification we are light in the Lord, Eph. 5.8. After the Fall the Will was depraved, there was not only impotency to Good, but obstinacy; now in Sanctification there is a blessed pliableness in the Will, it doth symbolize and comport with the Will of God. After the Fall the Affections were misplaced on wrong Objects, in Sanctification they are tuned into a sweet order and harmony, the Grief placed on Sin, the Love on God, the Joy on Heaven. Thus Sanctification spreads it self as far as Original Corruption. It goes over the whole Soul: The God of peace sanctify you wholly. He is not a consecrated Person who is good only in some part, but who is all over sanctified. Therefore in Scripture Grace is called a New Man, Col. 3.10. not a new Eye, or a new Tongue, but a new Man. A good Christian, though he be sanctified but in part, yet in every part.
