Being mad at God is not the same thing as not believing in Him. You can’t be mad at something that doesn’t exist, right? I believe God expects us to have a relationship with Him, and that relationship has many different dimensions. Like all relationships, it goes through ups and downs, and it matures over time. God made us fully human. We’re all sinners. We’re all flawed. He tests our faith for a reason. Getting mad at God is a way of expressing—and keeping—our faith.
