If God is willing to destroy evil but not able to, then he is not all powerful.
If God can destroy evil but chooses not to, then he is responsible for all evil.
If God can destroy evil and chooses to, then evil cannot exist.
If God is not able to and is not willing to destroy evil, then he is not God.
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?
-Epicurus
It's a work in progress - God is destroying evil.
Can God make a rock soooo large than even God cannot move it?
Can God microwave a burrito soooo hot that even God cannot eat it?
Can God make a circle that is shaped like a square?
"All powerful" only extends to the realm of "logically possible".
Love does not exist without free will.
Free will does not exist without both good and evil.
It is not "good" to take away someone's free will - hence present day evil.
(God would be "evil" if he forced everyone to be good)
The only way to create goodness is to allow all of us to eat from the tree of the "knowledge of good and evil", after which we will all eternally cling to what is good of our own free will and due to our own personal experience.
