And at the time of the offering of the oblation, Elijah the prophet came near and said, “O Lord, God of Abraham, Isaac, and Israel, let it be known this day that you are God in Israel, and that I am your servant, and that I have done all these things at your word.
The power of Elijah is summed up in this verse. Elijah knew God, heard God, knew his place as servant and did what God told him to do. Elijah was nothing more than a voice proclaiming what God was going to do. Elijah did not perform any miracles, he only obeyed God.
And you call upon the name of your god, and I will call upon the name of the Lord, and the God who answers by fire, he is God.” And all the people answered, “It is well spoken.”
God told Elijah to set the stage for this demonstration of faith. Elijah spoke and God answered. Elijah only spoke what God told him to say. That does not mean that Elijad held the power to make fire rain down from the sky.
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.
Here is how we can know that Elijah did not possess the power.
1 Kings 19:2-3 English Standard Version
2 Then Jezebel sent a messenger to Elijah, saying, “So may the gods do to me and more also, if I do not make your life as the life of one of them by this time tomorrow.” 3 Then he was afraid, and he arose and ran for his life and came to Beersheba, which belongs to Judah, and left his servant there.
Anyone who held the power of God within his control would not have feared for his own life and run from a threat.
The power of Elijah was his faith in God to hear, believe and obey.
It is no different for us today than it was for Elijah or John the Baptist or any of the apostles or saints before us. By faith, hear, believe and obey.
There are others who only seek power.
