Good post at Evangel by Ray Ortlund Jnr. Here is a flavour.
'Imagine the evangelical church without the gospel. I know this makes no sense, for evangelicals are defined by the evangel. But try to imagine it for just a moment. What might our evangelicalism, without the evangel, look like? We would have to replace the centrality of the gospel with something else, naturally. So what might take the place of the gospel in our sermons and books and cassette tapes and Sunday school classes and home Bible studies and, above all, in our hearts?
A number of things, conceivably. An introspective absorption with recovery from past emotional traumas, for example. Or a passionate devotion to the pro-life cause. Or a confident manipulation of modern managerial techniques. Or a drive toward church growth and “success.” Or a deep concern for the institution of the family. Or a fascination with the more unusual gifts of the Spirit. Or a clever appeal to consumerism by offering a sort of cost-free Christianity Lite. Or a sympathetic, empathetic, thickly-honeyed cultivation of interpersonal relationships. Or a determination to take America back to its Christian roots through political power. Or a warm affirmation of self-esteem. The evangelical movement, stripped of the gospel, might fix upon any or several of such concerns to define itself and derive energy for its mission. In other words, evangelicals could marginalize or even lose the gospel and still potter on their way, perhaps even oblivious to their loss.But not only is this conceivable, it is actually happening among us right now.
Whatever one may think of the various concerns noted above as alternatives to the centrality of the gospel—and some of these matters possess genuine validity and even urgency, especially the family—not one of them is central to our faith. Not one of them is the gospel or deserves to push the gospel itself to the periphery of our message, our agenda and our affections. But the gospel of our blessed Lord Jesus Christ is today suffering humiliation among us evangelicals by our conspicuous neglect of it.'
