John 3: 27 - 30

"John answered, 'No one can receive anything except what is given him from heaven. You yourselves bear me witness, that I said, I am not the Christ, but I have been sent before him. He who has the bride is the bridegroom; the friend of the bridegroom, who stands and hears him, rejoices greatly at the bridegroom's voice; therefore this joy of mine is now full. He must increase, but I must decrease."
