This is he who was spoken of through the prophet Isaiah: “A voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for him.’ ”
“I will send my messenger, who will prepare the way before me. Then suddenly the Lord you are seeking will come to his temple; the messenger of the covenant, whom you desire, will come,” says the Lord Almighty.
And he will go on before the Lord, in the spirit and power of Elijah, to turn the hearts of the parents to their children and the disobedient to the wisdom of the righteous—to make ready a people prepared for the Lord.”
