There will be evidences of God's patience with us and of his mercy towards us as we struggle with sin. And there will be evidences of his sustaining grace as we go through horrific physical suffering that Satan was the immediate cause of (as it says in the Bible: "This woman . . . whom Satan bound for eighteen years" [Luke 13:16]. She had this bent-over back, and Satan was doing it, and God was ordaining that he be allowed to do it). God ordains all of these things so that his gloryhis mercy, justice, grace, wisdomwould shine more brightly.
Now we can argue with that and say, "I don't agree. I don't think God should run the world this way." And if we ultimately disagree then we will reject God, we will reject the biblical testimony, and we will perish forever in hell. But I choose to trust him that his way of managing the devil and managing evil that comes at me is wiser than the way I might choose to manage it.
