26 They came to John, and said to him, “Rabbi, he who was with you beyond the Jordan, to whom you have testified, behold, the same baptizes, and everyone is coming to him.” 27 John answered, “A man can receive nothing, unless it has been given him from heaven. 28 You yourselves testify that I said, ‘I am not the Christ,’ but, ‘I have been sent before him.’ 29 He who has the bride is the bridegroom; but the friend of the bridegroom, who stands and hears him, rejoices greatly because of the bridegroom’s voice. This, my joy, therefore is made full. 30 He must increase, but I must decrease.
31 He who comes from above is above all. He who is from the Earth belongs to the Earth, and speaks of the Earth. He who comes from heaven is above all. 32 What he has seen and heard, of that he testifies; and no one receives his witness. 33 He who has received his witness has set his seal to this, that God is true. 34 For he whom God has sent speaks the words of God; for God gives the Spirit without measure. 35 The Father loves the Son, and has given all things into his hand. 36 One who believes in the Son has eternal life, but one who disobeys [1] the Son won’t see life, but the wrath of God remains on him.”

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.
