I'm not far enough into this book to know whether it's much good, but the opening lines of the Prologue show some promise:
The motto was 'Pax,' but the word was set in a circle of thorns. Pax: peace, but what a strange peace, made of unremitting toil and effort, seldom with a seen result; subject to constant interruptions, unexpected demands, short sleep at nights, little comfort, sometimes scant food; beset with disappointments and usually misunderstood; yet peace all the same, undeviating, filled with joy and gratitude and love. "It is My own peace I give unto you." Not, notice, the world's peace.
Learning to identify the "world's peace," and then repeatedly renounce it, is, I would say, always on the task list of a Christian disciple.
