What does James 5:17 mean?
In the previous verse, James wrote that the prayer of a righteous man is powerful and effective. Now he offers the example of the prayer of Elijah. Elijah was a prophet of God, but even so he was nothing more than a fallible, mortal, limited human man. And yet, when he prayed that it would not rain, it didn't rain.Of course, neither James's readers nor modern Christians easily think of Elijah as just an ordinary man. He was used by God to do amazing, miraculous things. This, though, is part of James's point. Elijah's power came from God, in response to Elijah's prayers.
There is no logical or spiritual reason for Christians not to pray, even when the situation seems dire. Why should we doubt that God can do powerful things in response to our prayers? We're not relying on some power within ourselves. We're not conjuring magic; we're asking God, and He is the one who is acting.
