Are you saying that God failed? Are you saying that God wanted Paul to save Israel but failed?
Paul escaped from Jerusalem by the skin of his teeth because he made such a noxious ass of himself to the Jews that he formerly was such a champion of, that he was under a death threat. Acts is most instructive. It also instructs us that Paul cannot get the circumstances of his salvation (surely it must be more important than a simple casual day) straight between chapter 9 and chapter 22.
The 12 disciples were still in Jerusalem, doing exactly what they were told to do by Christ, preach the kingdom gospel to Israel first and then the rest of the nations. But they weren't getting far, Israel wasn't accepting it.
