For this is he who was spoken of by Isaiah the prophet, saying, The voice of a man crying in the wilderness: Prepare ye the way of Lord. Make his paths straight.
Behold, I send my messenger, and he shall prepare the way before me. And LORD, whom ye seek, will suddenly come to his temple. And the messenger of the covenant, whom ye desire, behold, he comes, says LORD of hosts.
And he will go ahead, in front of him, in the spirit and power of Elijah, to turn back the hearts of fathers toward children, and the disobedient in a mentality of the righteous, to make ready for Lord a people prepared.
