Right now I’m engaged in a project taking a look at the metaphysics of prayer. Here is a quick summary of some of the issues involving Divine providence that I’m trying to parse out (courtesy of the very helpful SEP):
According to conservationism, while God conserves substances with their powers in existence, when creatures are causally active in bringing about their natural effects, God’s contribution is remote or indirect. In other words, God’s causal contribution consists in merely conserving the being or esse of the creature in question along with its power, and the causal activity of the creature is in some straightforward sense the creature’s own and not God’s (Freddoso 1991, 554). At the other end is occasionalism, where divine causal activity is maximal and creaturely causal activity is non-existent, since divine causal activity is the only type of genuine causality. Creatures provide at most an occasion for God’s activity, which is direct and immediate in bringing about all effects in nature. Concurrentism (or “divine concurrentism”) can then be seen as occupying the middle ground. Concurrentists hold that when a natural effect is produced, it is immediately caused by both God and the creature. God and the creature are both directly involved and “concur” in bringing about the natural effects typically attributed to the creature. (SEP)
