VIII. That the grace of the covenant is farther manifested, in that God has promised, and pursuant thereunto, gives his Holy Spirit to work faith, and all other graces that are connected with, or flow from it. That we have in the covenant of grace a promise of the Holy Spirit, to work in us, that grace which God requires, is very evident; for he says, _I will pour upon the house of David, and upon the inhabitants of Jerusalem, the Spirit of grace, and of supplications_, Zech. xii. 10. and elsewhere, God promises _to pour his Spirit upon their seed, and his blessings upon their offspring_, Isa. xliv. 3. and this is farther set forth, in a metaphorical way, when he promises _to sprinkle clean water_ on his people, and that _he would cleanse them from all their filthiness, and from all their idols, and give them a new heart, and put a new spirit within them, and take away the stony heart out of their flesh, and give them an heart of flesh_, and all this is said to be done by _his Spirit_, which he promised _to put within them_, Ezek. xxxvi. 25-27. And more particularly, the Spirit, as working faith in the hearts of believers, is called, for that reason, _The Spirit of faith_, 2 Cor. iv. 13. and all other graces are called, _The fruit of the Spirit_, Gal. v. 22, 23. so that they are from the Spirit, as the Author of all grace, and they proceed from faith, as one grace tends to excite another: thus the heart is said _to be purified by faith_, Acts xv. 9. which is said also _to work by love_, Gal. v. 6. and hereby we are enabled _to overcome the world_; and this produces all holy obedience, which is called, _The obedience of faith_, Rom. xvi. 26. Thus concerning the Spirit’s working faith and all other graces. Again, it is farther added, that the truth and sincerity of faith is evidenced as well as the grace of faith wrought by the Spirit; and this is also a blessing promised in the covenant of grace. Hereby we are enabled to discern our interest in Christ, and our right to all the blessings that accompany salvation; in which respect, the _secret of the Lord is with them that fear him, and he shews them his covenant_, Psal. xxv. 14. He not only discovers to them that there is such a dispensation of grace in general, but that they have a right to the blessings promised therein, and accordingly _seals them unto the day of redemption_, Eph. iv. 30. and hereby they are enabled to walk comfortably, as knowing in whom they have believed, and, are induced to the greatest thankfulness, as those, who are under the highest obligations to God, who promises and bestows these, and all other blessings, whereby his grace is abundantly manifested, in this covenant.
