From his autobiography Surprised by Joy and children's classic The Chronicles, from his poems and nvels, from his literary criticism and theologival explorations, C.S. Lewis has laid down, albeit unwittingly, a spirituality that the "mere Christian"-somthing of an invention of Lewis's-can live with from Monday through Saturday. On Sunday, Lewis would expect the mere Chritian to be in his or her own church. In this book, Bill Griffin, renowned Lewis scholar and biographer, captures the spirituality from Lewis's own writings and presents it in a manner reminiscent of Lewis's own. As Richard Foster writes: "Few people today could have accomplised what William Griffin has done in this work. He has exegeted for us a central feature of the life and thinking of C.S. Lewis, namely, his spirituality... and he has done it with zest and aplomb. I commemd it to you."
