It's not about *can't* believe, but *won't* believe.
Luke 16:27-31 "He [the rich man in hell] answered, 'Then I beg you, father, send Lazarus to my father's house, for I have five brothers. Let him warn them, so that they will not also come to this place of torment.'
"Abraham replied, 'They have Moses and the Prophets; let them listen to them.'
" 'No, father Abraham,' he said, 'but if someone from the dead goes to them, they will repent.'
"He said to him, 'If they do not listen to Moses and the Prophets, they will not be convinced even if someone rises from the dead.' "
If someone asked you to believe a rock was a god, would you refuse to believe it because you *can't* believe, or *won't* believe?
As for myself, I could try as hard as I might, but I could never believe a rock was a god. I can't believe your God either. No difference.
It would be very comforting to know deep in my soul that I was going to heaven when I die. I really *want* to believe that such a miracle would occur. But I cannot make myself believe it no matter how hard I try, because I understand how human faith operates, and that yours is no different than hundreds of other false faiths across the planet.
Barack Obama promises Democrats "hope", and they swoon and follow the new messiah. Your faith is no different. Belief in empty promises, because believing feels good. Obama is simply the new messiah, while yours is very old and the truth of his humanity is lost in the mists of time. No other difference.
