Paul's Vision of the Gospel and of Jesus as the Jewish Messiah

In Paul's vision, what happens in Jesus is that the brokenness of every tribe, of every people group, of every family gets focused on him. And he bears into himself the collective results of humanity. He shoulders the train wreck of human history and of human individual sin and human cultural pride. What kind of cross is he hanging on? Who put him up on the cross? Romans by the accusations of whom? The Jewish leaders who were compelling and were manipulating the Romans.
