EVERY believer must deal with the issue of theodicy at some point in their 'belief' journey. Some come up with excuses, others come to the only logical conclusion: god(s) does/do not exist.
Why on earth is that a problem to a believer who's god concept is either not omnipotent, not omniscient, or so far from human: it's intervention in human affairs is not to be expected?Epicurus' quote sums it up:
“Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?”
I'm not saying that a god exists in any of those forms, but people who believe one does, need pay no attention to the Epicurean Problem. It troubles only classical theology.
[That said, the Problem had a great impact upon me when I first heard it, believer in a all powerful butcher who claimed to be Love, as I was.]
