I've started reading N.T. Wright's new book, "Surprised By Hope, Rethinking Heaven, The Resurrection, and the Mission of the Church". There, Bishop Wright explains what he has come to see as "life after life after death"--the classic Christian doctrine of heaven and what it means for us, rather than the sentimentalized version prominant in popular culture (and even in some parts of Christian culture) today.
To see a brief video introduction of the concept, check out this interview of N.T. Wright by Stephen Colbert. Surprised by Hope: N.T. Wright on The Colbert Report.
Having been to four funerals within the past two months, the topic is relevant. I'll post more afer I finish.
