The ultimate proof that Christianity is false.
If God did not show himself/perfom miracles in front of EVEN ONE non believer before they died (and I'm talking about REAL miracles here, not seeing Jesus in a dream bullcrap) than that proves that either God did not care about that person or is incapable of performing miracles. I'm not just talking about the billions of people who died and went to hell/exist in another dimension, I'm talking about if EVEN ONE person did not personally see a supernatural reveleation of God. If 19 billion, 999 million, 999 hundred thousand, and 999 people went to heaven, while EVEN ONE went to hell through lack of belief, then either God chose not to reveal himself or couldn't. On the one hand, God is evil, on the other, he can't perform miracles. Now, of course, some Calvinist interpretation of God still could be true, but now let's think this out. Assuming we go with option A and God is evil, then you could argue it your moral duty to deliberately go to hell to reduce the suffering of damned souls, or go to heaven just to bring about a 2nd rebellion against the evil God, but even then you would just be going to heaven just to go back to hell or whatever. So, in conclusion, we can be 99.999999999 (add a googolplex 9s) certain that non-Universalist Christianity is false, but even if it is true than we probably still shouldn't believe. I can't believe nobody has thought of this argument before but here it is. You're welcome. Now go share it with your religous relatives.
