If God is unable to prevent evil, then he is not all-powerful.
If God is not willing to prevent evil, then he is not all-good.
If God is both willing and able to prevent evil, then why does evil exist?
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?
Isn’t there that philosophical argument about how God can’t be both all-good and all-powerful? If he’s all-good, he would have to stop bad things.
It’s been well over a decade since philosophy class, but this reminded me of that argument.
Forgot who made it though.
It’s the Epicurean Paradox https://en.m.wikipedia.org/wiki/Epicurean_paradox
In summary:
Epicurus.
