3:30 He must increase, but I must decrease - So they who are now, like John, burning and shining lights, must (if not suddenly eclipsed) like him gradually decrease, while others are increasing about them; as they in their turns grew up, amidst the decays of the former generation. Let us know how to set, as well as how to rise; and let it comfort our declining days to trace, in those who are likely to succeed us in our work, the openings of yet greater usefulness.
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.
