In the face of dramatic membership decline, John Leith calls on the church to say what no one else "can" say. Leith writes that too often sermons are moral exhortations which can be delivered more effectively at Rotary or Kiwanis clubs; or political and economic judgements on society presented with greater wisdom and passion at political conventions; or they offer therapies better provided by competent psychiatrists. He urges the church to use its only "unique" skill--the ability to interpret and apply the work of God through sermons, teaching, and pastoral care.
