John 3:27-30 King James Version (KJV)
27 John answered and said, A man can receive nothing, except it be given him from heaven.
28 Ye yourselves bear me witness, that I said, I am not the Christ, but that I am sent before him.
29 He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom's voice: this my joy therefore is fulfilled.
30 He must increase, but I must decrease.
