31 He that cometh from above is above all: he that is of the earth is of the earth, and of the earth he speaketh: he that cometh from heaven is above all. 32 What he hath seen and heard, of that he beareth witness; and no man receiveth his witness. 33 He that hath received his witness hath set his seal to [this], that God is true. 34 For he whom God hath sent speaketh the words of God: for he giveth not the Spirit by measure. 35 The Father loveth the Son, and hath given all things into his hand. 36 He that believeth on the Son hath eternal life; but he that obeyeth not the Son shall not see life, but the wrath of God abideth on him.
Matthew Henry's Commentary on John 3:31-36
Commentary on John 3:22-36
(Read John 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.
