He’s right about a lot of things, but soul sleep isn’t one of them.
Tom Wright’s scholarly writing on the biblical teaching on the resurrection of the dead is praiseworthy for a number of reasons. He has alerted the evangelical community to the unfortunate way in which popular theologies of “going to heaven” are eclipsing the biblical hope of the resurrection to eternal life. But he does have one major weak spot, in my view, and that is the rather poor treatment of the doctrine of “soul sleep.” Soul sleep is the view that people do not experience any conscious intermediate state of waiting between death and resurrection. They are wholly dead until God steps in and raises them back to life.
