If you read the Bishop's complete comments, you'll see that he says that those who are saved will be in the Presence of God from the time of their deaths. He's simply saying that this is not the "Heaven" commonly visualized in popular culture.
He then emphasizes the ultimate End of Time, the return of Jesus in glory, the resurrection of the living and the dead (the reunion of souls with bodies) and the New Heavens and New Earth restored through Christ.
I may have to get the book and read it.
