1 Kings 18:38-39 Then the fire of the LORD fell, and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that [was] in the trench. (39) And when all the people saw [it], they fell on their faces: and they said, The LORD, he [is] the God; the LORD, he [is] the God.
And KABOOM!!! The fire of the LORD fell and burned up the whole thing- sacrifice, wood, stones, water, and dust. In startling contrast to the mute response of the false idol Baal, God speaks and speaks mightily. The people fell on their faces and replied with the confession The LORD, he is the God! And then the prophets of Baal get their due.
1 Kings 18:40 And Elijah said unto them, Take the prophets of Baal; let not one of them escape. And they took them: and Elijah brought them down to the brook Kishon, and slew them there. (450 unbelievers/ mockers of God)
