8. The Spirit is promised, to cause us walk in his statutes, Ezek. xlvi. 27. Now all these promises are made good to us in Christ, who is the cautioner of the covenant; yea, he hath gotten now the dispensing and giving out of the rich promises of the covenant, committed unto him; so as he is the great and glorious custodier of all purchased blessings. 9. There are new waterings, breathings, and gales of the Spirit, given in Christ, Isa. xxvii. 3. He must water his garden or vineyard every moment. This is the north wind and the south wind that bloweth upon the garden, Cant. iv. 16. He must be as the dew unto Israel, Hos. xiv. 5. 10. Through Christ is the believer brought into such a covenant state, as giveth great ground of hope of certain victory. He is not now under the law, but under grace; and hence inferreth the apostle, Rom. vi. 14, "That sin shall not have dominion over them." Being now under that dispensation of grace, whereby all their stock is in the Mediator's hand, and at his disposal; and not in their own hand and power, as under the covenant of works, there is a sure ground laid down for constant supply and furniture in all necessities. 11. Christ hath prayed for this, John xvii. 17, "Sanctify them through thy truth;" where the Lord is praying, that his disciples might be more and more sanctified, and so fitted and qualified for the work of the ministry they were to be employed in. And what he prayed for them, was not for them alone, but also for the elect, proportionably, who are opposed to the world, for which he did not pray, verse 9. 12. He standeth to believers in relation of a vine, or a root, in which they grow as branches, so that by abiding in him, living by faith in him, and drawing sap from him, they bring forth fruit in him, John xv. 1, 2, 4, 5. Their stock of grace is in him, the root; and he communicateth sap and life unto his branches, whereby they grow, flourish, and bring forth fruit to the glory of God. 13. Christ hath taken on him the office of a prophet and teacher, to instruct us in the way wherein we ought to go; for he is that great prophet whom the Lord promised to raise up, and who was to be heard and obeyed in all things, Deut. xviii. 15. Acts iii. 22, and vii. 37. "He is given for a witness, and a leader," Isa. lv. 4; and we are commanded to hear him, Matt, xvii. 5. Mark x. 7. 14. He hath also taken on him the office of a king, Psal. ii. 6. Matt, xxviii. 5. Isa. ix. 7. Phil. ii. 8-11. and thereby standeth engaged to subdue all their spiritual enemies, Satan and corruption, Psal. cx. He is given for a leader and commander, Isa. lv. 5, and so can cause his people walk in his ways.
