 Would it ever be possible to know or reasonably believe that God has answered a particular petitionary prayer? As one might expect, philosophers disagree about this question. Some theists think that for all we know, for any particular event that happens, God may have had independent reasons for bringing that event about, so we cannot know whether or not God brought it about because of a prayer (as opposed to bringing it about for other reasons—for more on this argument, see Basinger 2004, Davison 2017, chapter 4, Choi 2016, and Davison 2022, chapter 4). This line of thought is especially interesting in light of the recent popularity of so-called skeptical theism, which responds to the problem of evil by claiming that we can never know exactly how particular events are connected with each other and with good or bad consequences, some of which may be beyond our understanding (see McBrayer 2010, Other Internet Resources). Others argue that as long as people are justified in believing, in general terms, that God sometimes answers prayers, then it is possible to believe reasonably that one’s petitionary prayer has been answered when one knows that the thing requested has come to pass (see Murray and Meyers 1994, Murray 2004, and Choi 2016).
