“Et ego nesciebam eum : sed qui misit me baptizare in aqua, ille mihi dixit : Super quem videris Spiritum descendentem, et manentem super eum, hic est qui baptizat in Spiritu Sancto.”
“And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost.”
“I myself did not know Him, but the One who sent me to baptize with water told me, ‘The man on whom you see the Spirit descend and rest is He who will baptize with the Holy Spirit.’”
“I didn’t recognize him, but he who sent me to baptize in water, he said to me, ‘On whomever you will see the Spirit descending, and remaining on him, the same is he who baptizes in the Holy Spirit.’”
“And I knew him not: but he that sent me to baptize in water, he said unto me, Upon whomsoever thou shalt see the Spirit descending, and abiding upon him, the same is he that baptizeth in the Holy Spirit.”
Saith John, According to the revelation which I had, when I received my extraordinary commission to baptize, so it fell out to me, I did see, when he was baptized, the heaven opening, and a representation of the Spirit of God (for no man can see God and live) descending. The form of the representation was like that of a dove. And it was not a mere transient sight, but it did for some time abide upon that person, in that sensible representation; by that token I knew that he was the Son of God.
(2.) That he was told to expect it, which very much corroborates the proof. It was not John's bare conjecture, that surely he on whom he saw the Spirit descending was the Son of God; but it was an instituted sign given him before, by which he might certainly know it (v. 33): I knew him not. He insists much upon this, that he knew no more of him than other people did, otherwise than by revelation. But he that sent me to baptize gave me this sign, Upon whom thou shalt see the Spirit descending, the same is he. [1.] See here what sure grounds John went upon in his ministry and baptism, that he might proceed with all imaginable satisfaction. First, He did not run without sending: God sent him to baptize. He had a warrant from heaven for what he did. When a minister's call is clear, his comfort is sure, though his success is not always so. Secondly, He did not run without speeding; for, when he was sent to baptize with water, he was directed to one that should baptize with the Holy Ghost. Under this notion John Baptist was taught to expect Christ, as one who would give that repentance and faith which he called people to, and would carry on and complete that blessed structure of which he was now laying the foundation. Note, It is a great comfort to Christ's ministers, in their administration of the outward signs, that he whose ministers they are can confer the grace signified thereby, and so put life, and soul, and power into their ministrations; can speak to the heart what they speak to the ear, and breathe upon the dry bones to which they prophesy. [2.] See what sure grounds he went upon in his designation of the person of the Messiah. God had before given him a sign, as he did to Samuel concerning Saul: "On whom thou shalt see the Spirit descend, that same is he." This not only prevented any mistakes, but gave him boldness in his testimony. When he had such assurance as this given him, he could speak with assurance. When John was told this before, his expectations could not but be very much raised; and, when the event exactly answered the prediction, his faith could not but be much confirmed: and these things are written that we may believe.
3. That this was he upon whom the Spirit descended from heaven like a dove. For the confirming of his testimony concerning Christ, he here vouches the extraordinary appearance at his baptism, in which God himself bore witness to him. This was a considerable proof of Christ's mission. Now, to assure us of the truth of it, we are here told (v. 32-34),
Verses 29-36 John saw Jesus coming to him, and pointed him out as the Lamb of God. The paschal lamb, in the shedding and sprinkling of its blood, the roasting and eating of its flesh, and all the other circumstances of the ordinance, represented the salvation of sinners by faith in Christ. And the lambs sacrificed every morning and evening, can only refer to Christ slain as a sacrifice to redeem us to God by his blood. John came as a preacher of repentance, yet he told his followers that they were to look for the pardon of their sins to Jesus only, and to his death. It agrees with God's glory to pardon all who depend on the atoning sacrifice of Christ. He takes away the sin of the world; purchases pardon for all that repent and believe the gospel. This encourages our faith; if Christ takes away the sin of the world, then why not my sin? He bore sin for us, and so bears it from us. God could have taken away sin, by taking away the sinner, as he took away the sin of the old world; but here is a way of doing away sin, yet sparing the sinner, by making his Son sin, that is, a sin-offering, for us. See Jesus taking away sin, and let that cause hatred of sin, and resolutions against it. Let us not hold that fast, which the Lamb of God came to take away. To confirm his testimony concerning Christ, John declares the appearance at his baptism, in which God himself bore witness to him. He saw and bare record that he is the Son of God. This is the end and object of John's testimony, that Jesus was the promised Messiah. John took every opportunity that offered to lead people to Christ.
