In seminary, we were exposed to theologians who did not believe that Jesus lphysically rose from the grave. My initial reaction was strongly negative. The more I listened, the more I learned to value their insights. It was false to say they didn't believe in the resurrection. They believed that resurrection was something other than the physical resuscitation of the body. It caused me to expand my own understanding of resurrection. If it is simply the return to life of one who was dead then why isn't Christ's resurrection viewed in the same light as Lazarus?
I have come to believe that resurrection is an act of validation. In crucifixion the world sought to deny the legitimacy of Jesus's claims. In the resurrection God weighed in and judged the argument in favor of Christ. And in that way, it is an act of Grace. It is an eternal offer for people to rethink their rejection of Christ and his way. The empty tomb remains an open door through which people who have resisted God can return.
