Pascal argues that it is rational to wager that God exists because we have everything to gain and nothing to lose. He presents a thought experiment where we are faced with an infinite distance separating us from the truth, and must place a bet on whether God exists or not without being able to know for certain. If we bet that God exists and we are wrong, we lose nothing, but if we are right, we gain eternal life. Therefore, the rational choice is to wager that God exists through faith and live according to God's commands.
