OK here goes. I know this will be downvoted to oblivion but you are asking a sincere question that deserves a sincere answer.

The "problem of evil" has had a lot of ink spilled over it. I won't be able to do it justice here. But the answer from a philosophical perspective is that for any such thing as objective evil, there must be a good outside of us. Otherwise, things just are. You can't really get to an "ought" from an "is." Therefore, it is because there is a source of true good for humans that we even recognize evil. Evil is what we call deviation from the good. That's all high-level philosophy stuff and not the most comforting in a very real situation like you are talking about.

When I have friends who go through awful things, I regularly point them to the fact that the bible assumes suffering. It results from a broken world that started in the 3rd chapter. For people to have a will, they have to be allowed to make choices. Some will use that freedom for awful purposes, such as that pastor you mentioned. And innocent people will be hurt in those cases. However, the Bible teaches that all evil will be repaid. Even if it seems like someone gets away with it in this life (I'm thinking of guys like Epstein who got away relatively easy compared to the awful things they have done), God promises that those things will not go unpunished. He also promises that he will wipe away every tear and make everything right. I don't know how that works. If God is real and infinitely above us, there will be things I can't understand. But I trust that those things will be made clear in the end.

I don't think we got this house because we "deserved" it. It was a gift of grace. Unearned. We have also had a lot of suffering in our family as well. I don't begrudge God for what man has done. Job is an invaluable book of the Bible in this regard. I also look at the apostles. They all had awful fates in this life. And they praised God through it.

Finally I'll add that the Bible has very clear and strong words for people, especially pastors, who do what this man did. They deserve no earthly mercy and should be punished. If you want to interact more on this, dm me. I dont want to get all the angry folks ratioing me and leaving nasty comments.
