First, there is no one to blame for the suffering. You may complain, but you have no right to complain and no one to complain to. In a godless universe there is no reason at all why there shouldn't be. Second, you have no one to turn to for strength to cope, other than your own limited resources or the resources of other humans who might, one hopes, care about your suffering. To rule out the existence of God raises a third problem.
Atheism turns out to be too simple.
If the whole universe has no meaning, we should never have found out that it has no meaning. Of course, whatever the problems of living without God, or whatever evidence there may be to the contrary, some are content to base their lives on that philosophy. In other words, as Russell clearly saw, if there is no God there is no ulimate meaning in anything. The option I will argue for is one that gives some meaning to the whole problem of suffering. It can also give one the courage to face it, the motivation to relieve it where possible, and the certainty of a final end to it.
