Theism vs. Deism: What's the Difference?
Quick Answer
"Theism" is the belief in a god or gods who are actively involved in the universe and in human affairs, often through revelation, prayer, or miracles. "Deism" is the belief in a god who created the universe but does not intervene in it afterward, leaving it to run according to natural laws, discoverable through reason rather than revelation.
