Pascal argued that if Christianity is wrong, you lose nothing, but if it is right then non-believers spend eternity in Hell. So what do you have to lose by believing?
What if Pascal was wrong? What if the real God has yet to reveal himself and punish all who believed in the God of Abraham, Isaac and Jacob. Then we have everything to lose by believing in the Judeo-Christian God.
When I see a sign that says “Bridge Out” I can take a detour and avoid driving into the water. If I doubt the veracity if the sign, I can stop my car and walk ahead to see if the bridge is really out. I cannot, however, walk up to a chasm and look to see if there really is a Hell. No one would tell me to unquestioningly heed every warning sign I come across. Why should I heed warnings of Hell?
