John 3:27-30

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.
