And Mary is Queen of Heaven. That makes her greater than John the Baptist. Since Jesus says that the least in Heaven is greater than John the Baptist, we know that when Jesus refers to John the Baptist, he is speaking about the Earthly greatness of John the Baptist, not the Heavenly greatness of John the Baptist, since John the Baptist did go to Heaven.
That's why Jesus says, "There has arisen (PAST TENSE) none greater than John the Baptist." Yet everyone who arises in Heaven arises to more greatness than what John had arisen to.
So Jesus lied? Who knew?
