1. God allows suffering only to the extent you reject Satan.
I have a problem with this one. It makes people feel like bad stuff happens to them because they weren't good enough . I prefer the Buddhist approach: "all suffering comes from desire".
As in, acceptance and appreciation for what you have are key. I apply it to my marriage by reminding myself that I got more good years out of my marriage than most, and three great kids. It's much better than focusing on the life I thought I would be having with my ex at this age.
