"Christians famously have the problem of pain: how can a benevolent and omnipotent god permit evil to exist? But atheists like myself have our own paradox to contend with: the problem of joy. Why do randomly good things happen?"
The question of "why bad things happen to good people", and how it is even possible that God would let his loved ones feel pain and suffering is an ongoing struggle. It takes pain and the experience of getting beyond that pain to truly understand why.
In reading this article by an Atheist I found the above quote truly interesting. Atheists, who don't have God or a Devil to blame for bad things, also have no one to attribute joy too. I 've never thought of that.
