And I saw,.... The Spirit descending from heaven as a dove, and lighting upon Jesus, and remaining some time on him; this he saw with his bodily eyes:

and bore record; at the same time, before all the people that were with him, when he baptized Jesus:

that this is the Son of God; the natural, essential, and eternal Son of God; who being sent in the fulness of time, had assumed an human nature, in which he became subject to all ordinances, and had the Spirit without measure bestowed on him; and which was an evidence who he was, and of what he came about.

I saw (ἑώρακα)

Rev., more strictly, according to the perfect tense, I have seen. See on John 1:32, and note the different verb for seeing, on which see on John 1:18.

Bare record (μεμαρτύρηκα)

Rev., have born witness. Also the perfect tense.

The Son of God

This is the proper reading, but one very important manuscript reads ὁ ἐκλεκτὸς, the chosen. By the phrase John means the Messiah. It has the same sense as in the Synoptic Gospels. Compare Matthew 11:27; Matthew 28:19. For the sense in which it was understood by the Jews of Christ's day, see John 5:18, John 5:19; John 10:29, John 10:30-36. The phrase occurs in the Old Testament only in Daniel 3:25. Compare Psalm 2:12. On υἱὸς, son, as distinguished from τέκνον, child, see on John 1:12.

And I saw, and bare record that this is {r} the Son of God.

(r) This word the points out to us some excellent thing, and makes a distinction between Christ and others, whom Moses and the prophets commonly call the sons of the most High.

1:32-34 I saw the Spirit descending from heaven like a dove. See Mt 3:16, and notes. It was revealed to John that the Christ would thus be revealed. Indeed it was the anointing of the Spirit that made Jesus the Anointed, the Christ.

1:34 I saw it - That is, the Spirit so descending and abiding on him. And testified - From that time.

1:29-36 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.
