Paul was sent forth as another apostle, to bring another message to a world of lost sinners: "the gospel of the grace of God." That is what the book of Acts is, a transition period from law to grace, from a kingdom of believers to a body of believers, and from the nation Israel to the oneness of Jews and Gentiles in one new man, the Church the Body of Christ.
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.
You can understand the differences between the 12 and Paul if you understand that their calling and their messages were different. One was to A NATION. And one was to THE NATIONS. One concerned prophecy. And one concerned a mystery.
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.
