Christians of Reddit, how do you defend your belief?

Edit: I apologize for using the word "defend"; I have never seen that as a negative word, but to those who have, again, I apologize. I should have asked for an apologetic stance as pointed out to me by user, "PatricioINTP".

I know that you are in the minority and, on Reddit, your believes are often ridiculed. Maybe we can have a safe place to discuss? Probably not, but I think it is worth a shot.

My question: How do you defend the classic Epicurus quote, "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?"
