And they took the bull that was given them, and they prepared it and called upon the name of Baal from morning until noon, saying, “O Baal, answer us!” But there was no voice, and no one answered. And they limped around the altar that they had made.
And as midday passed, they raved on until the time of the offering of the oblation, but there was no voice. No one answered; no one paid attention.
1 Kings 18:26, 29 (ESV)
Then the fire of the Lord fell and consumed the burnt offering and the wood and the stones and the dust and licked up the water that was in the trench. And when all the people saw it, they fell on their faces and said, “The Lord, he is God; the Lord, he is God.”
1 Kings 18:38-39 (ESV)
So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth.
Revelation 3:16 (ESV)
