How can God be both omnipotent and benevolent?
Either he can intercede and chooses not to, which makes him not benevolent, or he is benevolent, but incapable which makes him not omnipotent. It cannot be both ways.
The best I can understand it is this, and you may well dismiss it as illogical, but it's what I believe. Sometimes, my kids think I'm the meanest, most horrible mom on the planet, because I said no to them for something-or-other. Sometimes, I have the power to do the thing they ask, but I choose not to. I don't do this out of spite or meanness, but because I have a larger goal in mind or I see the big picture. Maybe my kid has been grouchy and horrible and mean and so I don't let him go to his friend's house, or I don't buy him the xyz thing, or whatever. In the short term, my kid would be happy if I let him. In the long run, I know it's not the best thing for him.
(these are terrible examples, I admit that. It's late, and I'm usually in bed at this time, and so my brain is not coming up with great examples, and I apologize).
But, the thing is, I see the big picture when it comes to my kids. So sometimes I deny them requests, sometimes I force them to do things they'd rather not do, sometimes I don't allow them to do things they'd prefer to do. Not because I'm mean, but because in the long run, they'll be better for it.
Sometimes, God does the same thing.
Again, yes, horrible examples, I know. Letting his people die at the hand of the Nazis is not the same thing as me not letting my kid go to a birthday party. I get that. I don't have big answers for what, exactly, did the Holocaust do to improve Jewish people. (short answer: I can think of nothing, and it was horrid and atrocious, and sometimes, I hate God for letting crap like that happen so someone else could learn compassion, or whatever the h--- reason he had for letting that happen. It makes no sense to me, at all). BUT, I have read through, and choose to believe, the Bible, including the Old Testament, and God let a lot of crappy things happen back then, too, *and yet* the crappy things ended up being stepping stones along a windy, long path to something better in the long run. And so, because I do believe the OT accounts were true, I choose also to believe that in the long run (and because I also believe the promises of the NT to be true), the crappy stuff of today will, eventually, lead to something better.
I can see this, in evidence in my own life. It hasn't been roses, I promise. Aspects of my life have royally sucked, big time. Hugely. Abuse, neglect, deaths, etc. I've hated a lot of it. But the person I am today was forged through those things, and the person I am today is a better person than who I was before those things. Did I enjoy getting here? Not so much. Am I yet grateful for the end result? I am. Do I understand why on earth God couldn't have just made me this better version of myself in the first place w/o all the sucky stuff?? No I sure as heck don't, but he didn't ask me, and I choose not to argue with him.
I can't explain it. Not in any way that will make sense to someone using logic, because it's not logical. I totally admit that. It's not. And I know that makes me sound like a loon, but I promise I'm really not. I just believe that God sees a bigger picture than me, and I trust Him with it, even when it sucks.
I don't think "having the power to prevent but choosing not to" automatically makes him not benevolent, *because he's looking at the spiritual well being of every single person on the planet, past, present, future, and we're seeing more the physical & emotional well being of the people here & now.* Because we (humans) judge his benevolence differently than he does, of course he seems not to be at times. I just choose (based on what I've seen in my life and in the Bible, which I choose to believe) that His way is greater than mine, and therefore the 2 terms are not contradictory even though they seem to be.
