Well if I’m wrong, then I’ll have to stand in judgment. The way I see it by my interpretations it will most likely go one of two ways. 1) Its too late, it was too late from the start; I believed what I believed, faking would have been a lie; I’m going to hell because he predetermined I was going to hell. 2) I’m provided the opportunity to apologize and repent my sins; and the gates of heaven are opened to me.I’ve found closing with that question usually shocks the crap out of most theists. Now if that doesn’t end the conversation, or chase them away; or you just want to keep them off-balance, be sure to ask them "What if you're wrong?"
Either way, there is noting I can do today to make ‘that scenario’ any different; because I’m not going to fake it for a “what if” and when faced with indisputable evidence I have no problem admitting I’m wrong. Additionally I’ve chosen to live my life the way I see fit; in a universally moral manner, not by the skewed outdated religious morals. I’ve chosen to live my life with a peace, balance and inner-spirituality that enriches my life and the lives of my friends and family. So if he has a problem with that, then maybe I have a problem with him. The real question then becomes, “Will I accept the offer of heaven?”
If you are wrong, you have wasted years of your life just in going to church. Thousands of Sundays (or Saturdays) plus all the other times you went. Time you could have spent with friends and family, enjoying nature, or working out to keep yourself in better health. Add to that the time you spent praying that you could have been doing instead. If you’re wrong, how much time have you wasted?By this point most theists have written me off as a lost cause and either never talk to me again or never talk religion to me again. I did have one guy respond “Holy shit! I never thought of that!” after overhearing my conversation (I don’t know if I deconverted him but it was apparently an eye opener).
Now what about all the people you pushed your beliefs upon, some joining you in your beliefs that are wrong, others alienated forever. What about all the children you scared into submission with stories of hell or promises of heaven. What about the truly good people you shunned because they believed something different.
On that note, what happens if you chose the wrong religion? What if Pagans or Buddhists have the right religion? Or what if Jesus was really a tool of the Devil?
