Malachi prophesied that before the Tribulation begins, Elijah will return:
“Behold, I will send you Elijah the prophet before the great and terrible day of Jehovah comes. And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers; lest I come and smite the earth with a curse” Malachi 4:5-6).
Elijah may appear during the time of “peace and safety.” He will do his work, but the nation of Israel will not respond to his ministry. Instead, they will sign the covenant with the Antichrist and suffer the consequences.
