John 3:26-30

And they came to John and said to him, “Rabbi, He who was with you beyond the Jordan, to whom you have testified, behold, He is baptizing and all are coming to Him.” John answered and said, “A man can receive nothing unless it has been given him from heaven. You yourselves are my witnesses that I said, ‘I am not the Christ,’ but, ‘I have been sent ahead of Him.’ 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. So this joy of mine has been made full. He must increase, but I must decrease.
