Should you believe there’s a God? To answer this, we might examine arguments for theism—like first-cause and design arguments—and arguments for atheism—like arguments from evil.

Pascal thought that evidence cannot settle the question of whether God exists, so he proposes that you should bet, or wager, on God because of what’s at stake: you have lots to gain and not much to lose. This article explains Pascal’s wager and considers three objections.
