Why don’t you ask him to show you? Perhaps he will.
I've tried time and again throughout my life and got nothing. Other than a sickness as a child, I've never prayed for anything for myself that I recall.
I used to believe death means non-existence. It's like before our Mother's egg was fertilized - we just didn't exist. However, I have come to think that once becoming a sentient being that we may have developed a connection to a supreme being in some manner.
I don't believe in a heaven or hell as in biblical terms. If anything, our connection or soul if you prefer melds with the creator of this amazing universe. That's why I'm an agnostic and not an atheist.
