Your response is surprisingly blithe. The usual evangelical position (the non-Reformed position) is that humans choose of their own free will whether to accept God's offer of salvation. Unfortunately, people are not in complete control over their beliefs. They are exposed so some facts and not others, to some misinformation and not others, and their unique experiences will lead them to consider some sources as more reliable than others, and different mental states will lead them, perhaps, to different conclusions from the facts that they accept.
So, in most cases, a person's non-belief in God is not under her control. She believes what she believes. So, if people are being divided between those who will go to heaven and those who go to hell, and if this division is, in part, based on what these people believe, then people are being rewarded or denied a reward on the basis of something that is not under their control.
Of course, the non-Reformed evangelical doesn't accept that God would work in such an arbitrary manner. I started this thread to ask evangelicals how they insist in claiming they know what motivates an atheist in her (presumably voluntary) non-belief in spite of her own statements to the contrary.
