1 Kings 18:41-44

Then Elijah told Ahab, “Go on up and eat and drink, for the sound of a heavy rainstorm can be heard.”  So Ahab went on up to eat and drink, while Elijah climbed to the top of Carmel. He bent down toward the ground and put his face between his knees.  He told his servant, “Go on up and look in the direction of the sea.” So he went on up, looked, and reported, “There is nothing.” Seven times Elijah sent him to look.  The seventh time the servant said, “Look, a small cloud, the size of the palm of a man’s hand, is rising up from the sea.” Elijah then said, “Go and tell Ahab, ‘Hitch up the chariots and go down, so that the rain won’t overtake you.’”

1 Kings 17:1 (NIV) says, "And Elijah the Tishbite, of the inhabitants of Gilead, said to Ahab, 'As the Lord God of Israel lives, before whom I stand, there shall not be dew nor rain these years, except at my word.'” 1 Kings 18:1 (NIV) says, "And it came to pass after many days that the word of the Lord came to Elijah, in the third year, saying, “Go, present yourself to Ahab, and I will send rain on the earth.” There has been no rain for years, and this is just one of many signs that the word of the Lord accomplishes what it sets out to do. Rain did not fall, and would not fall, until the Lord God decided it should fall, and moved Elijah to pray for rain in this passage. It is clear that God is not finished revealing who He is. Keep watch! God seeks to reveal Himself to you as well.
