No, the product we will seek naturally will not be the gospel. It will be a therapy of some kind, a technique for life, perhaps a way of connecting more deeply with our own spiritual selves on our own terms, terms that require no repentance and no redemption. It will not be the gospel. The gospel cannot be a product that the church sells because there are no consumers for it. When we find consumers, we will find that what they are interested in buying, on their own terms, is not the gospel.”
