Again, in this place of John ye have a testimony of the blessed trinity of persons, Father, Son, and Holy Ghost, in that holy unity of essence. The great point which John hath in hand is this fundamental of our salvation that Jesus Christ is the Son of God, and Saviour of the world, in whom all our confidence should be placed, and upon whom we should lean the weight of our souls. And this he proves by a two-fold testimony—one out of heaven, another in the earth. There are three bearing witness to this truth in heaven, “the Father the Word,” (that is, Jesus Christ, the eternal Son of God, whom this apostle calls the Word of God, or Wisdom of God, John i. 1) and the Holy Ghost. The Father witnessed to this truth in an audible voice out of heaven, when Christ was baptized, (Mat. iii. 17) “This is my beloved Son, in whom I am well pleased.” Here is the Father’s testimony of the Son when he was baptized which was given very solemnly in a great congregation of people, and divinely, with great glory and majesty from heaven, as if the heavens had opened upon him, and the inaccessible light of God had shined down on him This was confirmed in the transfiguration, (Mat. xvii. 5) where the Lord gave a glorious evidence—to the astonishment of the three disciples—how he did account of him—how all saints and angels must serve him, “him hath God the Father sealed,” saith John. Indeed, the stamp of divinity, of the divine image in such an excellent manner upon the man Christ, was a seal set on by God the father, signifying and confirming his approbation of his well beloved Son and of the work he was going about. Then the Son himself did give ample testimony of this. This was the subject of his preaching to the world, “I am the light and the life of men, he that believeth in me shall be saved.” And therefore he may be called the Word of God, (John i. 1) and the Wisdom of God, (Prov. viii.) because he hath revealed unto us the blessed mystery of wisdom concerning our salvation. He is the very expression and character of the Father’s person and glory, (Heb. i. 3) in his own person, and he hath revealed and expressed his Father’s mind, and his own office, so fully to the world that there should be no more doubt of it. Out of the mouth of these two witnesses this word might be established, but for superabundance, behold a third, the Holy Ghost witnessing at his baptism,—in his resurrection,—after his ascension. The Holy Ghost signifieth his presence and consent to that work, in the similitude of a dove, the Holy Ghost testifieth it in the power that raised him from the dead, the Holy Ghost put it beyond all question when he descended upon the apostles according to Christ’s promise. For the other three witnesses on earth, we shall not stay upon it, only know, that the work of the regeneration of souls by the power of the Word and Spirit signified by water, the justification of guilty souls signified by the blood of Jesus
