25Therefore a dispute arose on the part of John’s disciples with some Jews about purification.
26They came to John and said to him, “Rabbi, he who was with you beyond the Jordan, to whom you have testified, behold, he baptises, and everyone is coming to him.”
27John answered, “A man can receive nothing unless it has been given him from heaven.
28You yourselves testify that I said, ‘I am not the Christ,’ but, ‘I have been sent before him.’
29He 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. Therefore my joy is made full.
30He must increase, but I must decrease.
