There’s a series of questions which I’ve always found useful. It’s fascinating how often people don’t think about those little things that they believe.
“First of all, do you believe in Hell? Do you believe in an actual place where sinners are tormented for eternity?”
If that answer is “yes,” we can then move on to “Do you believe that God is an all-powerful, all-knowing being who created the universe and everything in it? Who sees the smallest sparrow fall, and knows everything – what has happened and what will happen?”
At that point, you need to point out that God is a sadist, who keeps a torture chamber in his basement just for kicks.
See, if this God person knows what will happen, then, first of all, “free will” is an illusion. He’s stacked the deck, because He knows exactly how you’re going to choose.
That being said, He chose to make you (since God, we have established, made us all) as a sinner, destined to go to Hell. He, in fact, made you that way. Brought you into existence in order that you would be tormented for all eternity.
So apparently God likes torture. In fact, He makes people for the sole purpose of being tortured.
And you want to pray to this Guy?
