5. So hath he procured, and worketh in the soul those graces that promove and carry on this work of sanctification and purifying; such as faith, which purifieth the heart, Acts xv. 9; whereof he is the author and finisher, Heb. xii.; and hope, which whosoever hath, "purifieth himself, even as he is pure," 1 John iii. 3.
6. He hath confirmed and ratified all the promises of the covenant, which are ample and large, touching this cleansing and washing, Jer. xxxv. 8, "And I will cleanse them from all their iniquity, whereby they have sinned against me." Ezek. xxxvi. 25, "Then will I sprinkle clean water upon you, and ye shall be clean from all your filthiness." So Ezek. xxxvii. 23, "and I will cleanse them." And all the other promises of the covenant, apprehended by faith, have no small influence on our cleansing; 2 Cor. vii. 1. "Having therefore these promises, let us cleanse ourselves," &c.; all which promises are yea and amen in Christ, 2 Cor. i. 20.
Thus Christ made all sure, for the cleansing and washing of his people, conform to that article of the covenant of redemption, "so shall he sprinkle many nations," Isa. lii. 15.
Secondly, As to the way of our use-making of Christ for the purging away of our filth and daily pollutions, believers would take this course:
1. They would remember and live in the conviction of the exceeding abominableness and filthiness of sin, which is compared to the vomit of a dog, and to the mire wherein the sow walloweth, 2 Pet. ii. 22; filthy rags, Isa. lxiv. 6; to a menstruous cloth, Isa. xxx. 22, and the like, that this may move them to seek with greater care and diligence, to have that filth taken away.
2. They would remember also how abominable sin makes them in the eyes of an holy God, "who cannot behold iniquity," being a God of purer eyes than to behold it, Hab. i. 13; nor can he look on it; and how therefore no thing can enter into the New Jerusalem, nor any thing that defileth. And this will make them so much the more to abhor it, and to seek to be washed from it.
3. They would look by faith on the blood of Christ that is shed for this end, to wash filthy souls into; and run to it as a fountain opened for this end, that they might come to it, and wash and be clean.
4. For their encouragement, they would grip by faith to the promises of the new covenant, which are large and full.
5. And remember the end of Christ's death, viz., to purchase to himself a holy people, zealous of good works, to present them to himself holy, and without spot or wrinkle, or any such thing; and this will be further ground of encouragement.
6. They would put the work by faith in his hand, who hath best skill to wash a foul soul, and to purge away all their spots; and by faith pray for and expect the Spirit to sanctify and cleanse them from all their filthiness; that is, they would make known and spread forth their abominations before the Lord, and eyeing Christ as the only great High Priest, whose blood is a fountain to wash in, would lay the work on him, and by faith put him to wash away that filth, and to purify their souls by his Spirit, pardoning their bygone iniquities and renewing them in the Spirit of their minds by grace, that they may walk before him in fear. Thus they would roll the work on him, and leave it there.
