3:29 The bride. The Church.
The bridegroom. Christ.
The friend of the bridegroom... rejoiceth. John already rejoices in the prospect of the union of the Bridegroom and Bride.
3:29 He that hath the bride is the bridegroom - He whom the bride follows. But all men now come to Jesus. Hence it is plain he is the bridegroom. The friend who heareth him - Talk with the bride; rejoiceth greatly - So far from envying or resenting it.
3:22-36 John was fully satisfied with the place and work assigned him; but Jesus came on a more important work. He also knew that Jesus would increase in honour and influence, for of his government and peace there would be no end, while he himself would be less followed. John knew that Jesus came from heaven as the Son of God, while he was a sinful, mortal man, who could only speak about the more plain subjects of religion. The words of Jesus were the words of God; he had the Spirit, not by measure, as the prophets, but in all fulness. Everlasting life could only be had by faith in Him, and might be thus obtained; whereas all those, who believe not in the Son of God, cannot partake of salvation, but the wrath of God for ever rests upon them.
