Dennis Prager (Jewish) does a fantastic job of taking apart atheism on the issue of suffering:
“The dead do not suffer” is atheism’s consolation to the parents of murdered children? This sentiment can provide some consolation — though still nothing comparable to the affirmation of an afterlife — to those who lose a loved one who had been suffering from a debilitating disease. But it not only offers the parents of Sandy Hook no consolation, it actually (unintentionally) insults them: Were these children suffering before their lives were taken? Would they have suffered if they had lived on? Moreover, it is the parents who are suffering, so the fact that their child isn’t suffering while decomposing in the grave is of no relevance.
And, most germane to our subject, this atheist message offers no consolation at all when compared to the religious message that we humans are not just matter but possess eternal souls.
