[There is yet another work of the Holy Spirit, not immediately in and upon the person of the Lord Christ, but towards him, and on his behalf, with respect unto his work and office; and it compriseth the head and fountain of the whole office of the Holy Spirit towards the church. This was his witness-bearing unto the Lord Christ,—namely, that he was the Son of God, the true Messiah, and that the work which he performed in the world was committed unto him by God the Father to accomplish.
…chose twelve apostles to bear testimony unto the holiness of his life, the truth and purity of his doctrine, the accomplishment of the prophecies of the Old Testament in his birth, life, work, and death; and, in especial, unto his resurrection from the dead, whereby he was justified and acquitted from all the reproaches of hell and the world,
…The first principal end why God gave the Holy Spirit to work all those miraculous effects in them that believed in Jesus, was, to bear witness unto his person that he was indeed the Son of God, owned and exalted by him;
…“I will,” saith he, “send the Comforter unto you. And when he is come, he will reprove the world of sin, and of righteousness, and of judgment: of sin, because they believe not on me; of righteousness, because I go to my Father, and ye see me no more; of judgment, because the prince of this world is judged,” John 16:7–11. The reason why the world believed not on Christ was, because they believed not that he was sent of God, chap. 9:29.
…for it was upon his ascension and exaltation that he received and poured out the promise of the Spirit to this purpose, Acts 2:33.]
[And we are to learn thus to know him,—
First, That we may love him with a pure unmixed love.
…consider his human nature, as it was rendered beautiful and lovely by the work of the Spirit of God upon it, before described. Do you love him because he was and is so full of grace, so full of holiness, because in him there was an all-fulness of the graces of the Spirit of God? Consider aright what hath been delivered concerning him, and if you can and do, on the account thereof, delight in him and love him, your love is genuine and spiritual; but if your love be merely out of an apprehension of his being now glorious in heaven, and there able to do you good or evil, it differs not much from that of the Papists, whose love is much regulated in its actings by the good or bad painting of the images whereby they represent him.
Secondly, We are to know Christ so as to labour after conformity unto him. And this conformity consists only in a participation of those graces whose fulness dwells in him. We can, therefore, no other way regularly press after it, but by an acquaintance with and due consideration of the work of the Spirit of God upon his human nature; which is therefore worthy of our most diligent inquiry into.]
