One of the most common questions people ask Christians is how a good, all-knowing and all-powerful God could allow evil in the world.
The problem of evil in the world and why a righteous God would allow it, troubled the prophet Habakkuk.
Hab 1:13 Your eyes are too pure to look on evil; you cannot tolerate wrongdoing. Why then do you tolerate the treacherous? Why are you silent while the wicked swallow up those more righteous than themselves?
In “De Ira Dei” the early Christian writer Lactantius attributes a variant of the following paradox to the Greek philosopher Epicurus:
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?
