Most assuredly I tell you, we speak that which we know, and testify of that which we have seen, and you don't receive our witness.
And John answered and said, A man can receive nothing, except it is given to him from heaven. Ye yourselves bear me witness, that I said, I am not the Messiah, but that I was sent before him. He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and hears him, rejoices greatly because of the bridegroom's voice: and this my joy therefore is fulfilled. For He must increase, and I must decrease ( John 3:27-30 ).
