“See, I am going to send my messenger, and he will clear the way before me. Then the Lord you seek will suddenly come to his temple, the Messenger of the covenant you delight in #— #see, he is coming,” says the Lord of Armies.
And he will go before him in the spirit and power of Elijah, to turn the hearts of fathers to their children, and the disobedient to the understanding of the righteous, to make ready for the Lord a prepared people.”
