Here is an excellent review from Greg Gilbert on the Nooma video series from Rob Bell. Even though Rob is an effective communicator it seems that he is preaching and teaching a false gospel. I know those are strong words but when the gospel is only presented as a half truth then it leads to a no truth which results in a lie. The details about Bell and his theology is reflected in the series and this review gives one an excellent breakdown.
