Elijah stood against the idolatry of Israel in the days of Ahab and Jezebel. At his word it did not rain for three and a half years (1Kings 17:1). This was God's judgment against His backslidden people.
After three and a half years of drought and famine, the word of the Lord came to Elijah once again. He was to show himself to king Ahab, because God was about to send rain (1Kings 18:1).
Before God could send rain, the people had to repent of the sin that had placed them under the judgment of God. They had to put away their idols, they had to chose whom they would serve (1Kings 18:21). In a remarkable trial by fire, baal was proven to be no god at all, and The Lord God was shown to be the one and only God (1Kings 18:20-40).
With the sin dealt with, Elijah prays for rain. Seven times he sends his servant to look before he sees a cloud the size of a man's hand (1Kings 18:42-44). This cloud grew until the sky was black resulting in a heavy shower.
You may look at this biblical event, as well as other miraculous accounts, and feel that God only used special people to do extraordinary things. He used "super apostles" like Paul, and the disciples to do amazing things.
The bible tells us that Elijah was a man with a nature like ours (James 5:16-18). He was no different than you or I. God has chosen each one of us to do things for Him in advancing His kingdom. Some are pastors, teachers, evangelists. Others are witnesses in the home and in the workplace. The passage in James 5 is talking about prayer. We need men and women with the kind of faith that Elijah had when he prayed down fire, and then prayed down rain.
God desires to send the fire of His Spirit to cleanse and purify His people. He desires to send the refreshing rain of His presence to a dry and weary land. He is not looking for a great individual to use. He is looking for an individual full of faith, and willing to be used in any way.
God will send revival. Will it come through you?
