God vs. Baal

In the 18th chapter of 1 Kings, the Lord told Elijah to show himself to Ahab, for the Lord will send rain upon the earth, ending a severe famine.

Ahab was skeptical at first.  He called Elijah a troubler.  But Elijah told Ahab that it was Ahab who troubled Israel by abandoning the Lord's commandments.  Ahab gathered 450 prophets of Baal onto Mount Carmel.  Elijah told the Baal followers to command that their god Baal answer their prayers.  So they cried out to Baal, over and over again.

Their prayers were never answered.

Elijah built an altar to the Lord, sacrificed a bull, and drenched it with water.  Elijah prayed to the Lord and the Lord answered by showering fire onto the bull offering, licking up all of the water.

Those who saw this fell on their faces.  Then, they slaughtered the prophets of the false god Baal.
