John 3:31

in honour, and dignity, and reputation in the world; he is the rising sun, (to give you notice of which I was but as the morning star), he must shine every day more and more. God hath indeed used me as a prophet, yea, more than a prophet, not to foretell Christ alone, but to point him to you. I have had my time, and finished my course, and God hath given me a reputation proportioned to the work he gave me to do, and to the time in which I was to work; but I must every day decay, and grow less and less, as Christ increaseth and groweth more and more.

He that cometh from above, meaning Christ. He that is of the earth, meaning himself, is from the earth,[2] is earthly, is but a frail and infirm man; and so speaketh as from the earth: this seems rather the sense, than that he speaketh of, or concerning the earth. See the Greek text. (Witham)

(1.) He instructs them concerning the dignity of Christ's person (v. 31): He that cometh from above, that cometh from heaven, is above all. Here, [1.] He supposes his divine origin, that he came from above, from heaven, which bespeaks not only his divine extraction, but his divine nature. He had a being before his conception, a heavenly being. None but he that came from heaven was fit to show us the will of heaven, or the way to heaven. When God would save man, he sent from above. [2.] Hence he infers his sovereign authority: he is above all, above all things and all persons, God over all, blessed for evermore. It is daring presumption to dispute precedency with him. When we come to speak of the honours of the Lord Jesus, we find they transcend all conception and expression, and we can say but this, He is above all. It was said of John Baptist, There is not a greater among them that are born of women. But the descent of Christ from heaven put such a dignity upon him as he was not divested of by his being made flesh; still he was above all. This he further illustrates by the meanness of those who stood in competition with him: He that is of the earth, is earthly, ho on ek tes ges, ek tes ges esti—He that is of the earth is of the earth; he that has his origin of the earth has his food out of the earth, has his converse with earthly things, and his concern is for them. Note, First, Man has his rise out of the earth; not only Adam at first, but we also still are formed out of the clay, Job 33 6. Look to the rock whence we were hewn. Secondly, Man's constitution is therefore earthly; not only his body frail and mortal, but his soul corrupt and carnal, and its bent and bias strong towards earthly things. The prophets and apostles were of the same mould with other men; they were but earthen vessels, though they had a rich treasure lodged in them; and shall these be set up as rivals with Christ? Let the potsherds strive with the potsherds of the earth; but let them not cope with him that came from heaven.

Verses 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.
