 For I'm going to do something in your days that you would never believe, even if someone had told you. The scriptures themselves are fulfilled in Jesus, the Son of God. And Paul, he doesn't want them to believe this or understand this merely in the context of, oh, that's a good history lesson. Now I know what the Old Testament is about. Now I understand the pattern of what Israel was meant to go through. No, he's pushing them to believe this in a very personal way.
