Paul said the hope of Israel was the resurrection. Israel was apparently dead in some sense and longed to be revived. What was the death that afflicted Israel? Are to believe that Paul, a physically alive Israelite, wished for physically dead children of Israel to be brought back to physical life? Was resuscitation from physical death the great hope of Israel to which Paul referred before King Agrippa in Acts 26?
I seriously doubt it. Israel was dead alright, having been killed by the law (I Corinthians 3). What they needed was freedom from the deadly aspect of law keeping, the propensity to judge and condemn other people. A law promoted self righteousness was the poison that killed Israel. The hoped for resurrection involved forsaking judgment of others and thereby escape their own personal judgment.
