I come now to speak a little to the other part of sanctification, which concerneth the change of our nature and frame, and is called vivification, or quickening of the new man of grace; which is called the new man, as having all its several members and parts, as well as the old man; and called new, because posterior to the other; and after regeneration is upon the growing hand, this duty of growing in grace, as it is called, 2 Pet. iii. &c. is variously expressed and held forth to us in Scripture; for it is called "an abiding and bringing forth fruit in Christ," John xv. 5; "adding to faith virtue, and to virtue knowledge," 2 Pet. i. 5, 6, 7; "a going on to perfection," Heb. vii. 1; "a growing up in Christ in all things," Eph. iv. 15; "a working out our salvation," Phil. ii. 12; "a perfecting of holiness," 2 Cor. vii. 1; "a walking in newness of life," Rom. vi. 4; "a yielding of ourselves unto God, as alive from the dead, and our members as instruments of righteousness unto God," Rom. vi. 13, 18; "a bringing forth fruit unto God," Rom, vii. 4; "a serving in newness of spirit," Rom. vii. 6; "a being renewed in the spirit of our minds, and a putting on the new man, which after God is created in righteousness and true holiness," Eph. iv. 23,24. Col. iii. 10, and the like: some whereof do more immediately express the nature of this change, as to the root, and some as to the fruit and effects thereof, and some the progress and advancement that is made or to be made therein. And all of them point out a special piece of work, which lieth on all that would see the face of God, viz. to be holy, gracious, and growing in grace. This, then, being a special piece of the exercise and daily work of a Christian, and it being certain, as some of the places now cited do also affirm, that without Christ they cannot get this work either begun or carried on, the main difficulty and question is, How they are to make use of Christ for this end? For answer whereunto, though by what we have said in our former discourse, it may be easy to gather what is to be said here; yet I shall briefly put the reader in mind of those things, as useful here.
