1 Kings 18:36-39 NIV

[36] At the time of sacrifice, the prophet Elijah stepped forward and prayed: “LORD, the God of Abraham, Isaac and Israel, let it be known today that you are God in Israel and that I am your servant and have done all these things at your command. [37] Answer me, LORD, answer me, so these people will know that you, LORD, are God, and that you are turning their hearts back again.” [38] Then the fire of the LORD fell and burned up the sacrifice, the wood, the stones and the soil, and also licked up the water in the trench. [39] When all the people saw this, they fell prostrate and cried, “The LORD—he is God! The LORD—he is God!”
