Jesus Christ also explained to his disciples that John’s coming was a fulfillment of the prophecy at Malachi 4:5, 6, that God would send Elijah the prophet before the coming of the great and fear-inspiring day of Jehovah.
... Nevertheless, great as John was (“Among those born of women there has not been raised up a greater than John the Baptist”), he would not be one of “the bride” class who will share with Christ in his heavenly Kingdom rule (Re 21:9-11; 22:3-5), for, Jesus said, “a person that is a lesser one in the kingdom of the heavens is greater than he is.” (Mt 11:11-15; 17:10-13; Lu 7:28-30)
