John 3:27-30

27John replied, “A man can receive nothing [he can claim nothing at all] unless it has been granted to him from heaven [for there is no other source than the sovereign will of God].

28You yourselves are my witnesses that I stated, ‘I am not the Christ (the Messiah, the Anointed),’ but, ‘I have [only] been sent ahead of Him [as His appointed forerunner and messenger to announce and proclaim His coming].’

29He who has the bride is the bridegroom; but the friend of the bridegroom, who stands by and listens to him, rejoices greatly because of the bridegroom’s voice. So this pleasure and joy of mine is now complete.

30He must increase [in prominence], but I must decrease.
