As a theist, say a Christian, how would you deal with the following scenario?
You have an adult son who you love dearly even though he has left the Church and declared himself to be an atheist. He is suddenly killed in a road accident.
Your kindly Church brethren console you by saying that your son will be waiting in Heaven where you will be reunited when you come to pass.
However, according to your belief, your son won't be going to Heaven, will he? In fact, he will be going to Hell for eternal punishment and torture.
How do you cope with the fact that you will be going to Heaven for eternity whilst knowing that your own son is down below suffering eternal damnation?
How could you possibly enjoy your afterlife or even live with yourself in the afterlife?
