I am confident Elijah was a human being but I’m not so sure about “quite like us.” On the other hand he was fully dependent on God for rain or lack thereof in the same way that those who suffer pray and those who are cheerful rejoice. There may be some who think it is the righteousness of the one who prays that determines the outcome but I prefer to believe the “powerful and effective” nature of the prayer has more to do with persistence in the face of circumstances beyond one's control. We know that we were not meant to live forever in bodies of flesh and blood and bones and so the healing that happens in the temporal is not nearly as “powerful and effective” as the healing that allows one to take life as it comes without being overcome. Every day is a gift despite the difficulties we face when we recognize we are in this thing together. So Elijah was indeed just like us even though some folks that farm and ranch in west Texas might like to have his ability to make it rain.
