I always told them “If you’re right, I black out into the void and never know I was wrong. If I’m right, you’ll have an eternity to regret it” ;)
If you and I both die today, and you are correct that there is no God, then neither of us are going to know it. We both are just dead and gone and worm food in the dirt. BUT, if I am right, and I know that I am, then we BOTH ARE GOING TO KNOW IT. Because I will be in His presence and you will be in hell. And we both will know it! So, you'd better be right. You get ONE chance to make the call.
