It was of him that the prophet Isaiah had spoken when he said: “A voice of one crying out in the desert, ‘Prepare the way of the Lord, make straight his paths.’”
Now I am sending my messenger— he will prepare the way before me; And the lord whom you seek will come suddenly to his temple; The messenger of the covenant whom you desire— see, he is coming! says the Lord of hosts.
He will go before him in the spirit and power of Elijah to turn the hearts of fathers toward children and the disobedient to the understanding of the righteous, to prepare a people fit for the Lord.”
