If god is all powerful (omnipotent) he able to do away with evil.
If god is all knowing (omniscient) he knows there is evil in the world.
If god is love (benevolent) he would see the evil and defeat it.
Therefore if god is omnipotent and does not defeat evil he is not omniscient or not benevolent. If he is omniscient and does not defeat evil he is not omnipotent or not benevolent. If he is benevolent and does not defeat evil he is not omnipotent or not omniscient.
I stumbled across this site here . Although this is an old argument it is worth revisiting.
As I study and move along on my journey I find more questions than answers.
