Religion

He is so far beyond us with our limited intelligence to be defy our ability to comprehend.

You state this as if it were a fact. How do you know this?

God could have chosen to create a world without violence or hardship but that would have been a heaven

Which, according to believers, exists and is real. So why not just create heaven and be done?

I personally believe that our life is a test and that good people despite their religion will see a better future after death.

How much of a "test" has life been for the infant who dies shortly after death? How much of a test has it been for Dick Cheney, who has lived a comfortable life with no sacrifices?

One last thing - you said atheists "refuse to believe in a God". I find your use of the word "refuse" to be disturbing. It implies that atheists recognize valid evidence for gods but actively reject it. It carries negative connotations, that there must be ulterior motives atheists have for simply believing in one less god than you do.
