3:14 John forbad him. The objection that John made to the baptism of Christ implies some knowledge of him. Their mothers were cousins, but there is no evidence that Jesus and John had ever met. The Spirit had told John to proclaim the Redeemer and had given him a sign by which he should know him. When Jesus came before him, he perhaps knew, by the Spirit, his purity, and may have believed that he was the Messiah, but as yet he knew him not (Joh 1:33). He could not be certain until he saw the Divine sign.
I have need to be baptized of thee. These words were uttered under the conviction, not certainty, that Jesus was the Christ.
3:13-17 Christ's gracious condescensions are so surprising, that even the strongest believers at first can hardly believe them; so deep and mysterious, that even those who know his mind well, are apt to start objections against the will of Christ. And those who have much of the Spirit of God while here, see that they need to apply to Christ for more. Christ does not deny that John had need to be baptized of him, yet declares he will now be baptized of John. Christ is now in a state of humiliation. Our Lord Jesus looked upon it as well becoming him to fulfil all righteousness, to own every Divine institution, and to show his readiness to comply with all God's righteous precepts. In and through Christ, the heavens are opened to the children of men. This descent of the Spirit upon Christ, showed that he was endued with his sacred influences without measure. The fruit of the Spirit is love, joy, peace, long-suffering, gentleness, goodness, faith, meekness, temperance. At Christ's baptism there was a manifestation of the three Persons in the sacred Trinity. The Father confirming the Son to be Mediator; the Son solemnly entering upon the work; the Holy Spirit descending on him, to be through his mediation communicated to his people. In Him our spiritual sacrifices are acceptable, for He is the altar that sanctifies every gift, 1Pe 2:5. Out of Christ, God is a consuming fire, but in Christ, a reconciled Father. This is the sum of the gospel, which we must by faith cheerfully embrace.
