The sum of the blessings Christ sought, by what he did and suffered in the work of redemption, was the Holy Spirit. So is the affair of our redemption constituted; the Father provides and gives the Redeemer, and the price of redemption is offered to him, and he grants the benefit purchased; the Son is the Redeemer that gives the price, and also is the price offered; and the Holy Spirit is the grand blessing, obtained by the price offered, and bestowed on the redeemed. The Holy Spirit, in his indwelling, his influences and fruits, is the sum of all grace, holiness, comfort and joy, or in one word, of all the spiritual good Christ purchased for men in this world: and is also the sum of all perfection, glory and eternal joy, that he purchased for them in another world. The Holy Spirit is that great benefit, that is the subject matter of the promises, both of the eternal covenant of redemption, and also of the covenant of grace; the grand subject of the promises of the Old Testament, in the prophecies of the blessings of the Messiah's kingdom; and the chief subject of the promises of the New Testament; and particularly of the covenant of grace delivered by Jesus Christ to his disciples, as his last will and testament, in the John 14, John 15 and John 16 chapters of John; the grand legacy, that he bequeathed to them in that his last and dying discourse with them. Therefore the Holy Spirit is so often called "the Spirit of promise," and emphatically "the promise, the promise of the Father," etc. (Luke 24:49; Acts 1:4 and Acts 2:33, Acts 2:39; Galatians 3:14; Ephesians 1:13 and Ephesians 3:6).

This being the great blessing Christ purchased by his labors and sufferings on earth, it was the blessing he received of the Father, when he ascended into heaven, and entered into the Holy of Holies with his own blood, to communicate to those that he had redeemed. John 16:7, "It is expedient for you, that I go away; for if I go not away, the Comforter will not come; but if I depart, I will send him unto you." Acts 2:33, "Being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this which ye now see and hear." This is the sum of those gifts, which Christ received for men, even for the rebellious, at his ascension. This is the sum of the benefits Christ obtains for men by his intercession (John 14:16–17). "I will pray the Father, and he shall give you another Comforter, that he may abide with you forever; even the Spirit of truth." Herein consists Christ's communicative fullness, even in his being full of the Spirit, and so "full of grace and truth" [John 1:14], that we might of "this fullness receive, and grace for grace" [John 1:16]. He is "anointed with the Holy Ghost" [Acts 10:38]; and this is the ointment that goes down from the head to the members. "God gives the Spirit not by measure unto him" [John 3:34], that everyone that is his "might receive according to the measure of the gift of Christ" [Ephesians 4:7]. This therefore was the great blessing he prayed for in that wonderful prayer, that he uttered for his disciples and all his future church, the evening before he died (John 17): the blessing he prayed for to the Father, in behalf of his disciples, was the same he had insisted on in his preceding discourse with them: and this doubtless was the blessing that he prayed for, when as our high priest, he "offered up strong crying and tears," with his blood (Hebrews 5:6–7). The same that he shed his blood for, he also shed tears for, and poured out prayers for.
