Every Christian--as he explores the historical record of Scripture and tradition and comes to a deep, abiding faith--experiences that Christ is the risen one and that he is therefore the eternally living one. It is a deep, life-changing experience. No true Christian can keep it hidden as a personal matter. For such an encounter with the living God cries out to be shared--like the light that shines, like the yeast that leavens the whole mass of dough.
