This encyclopedia covers almost every conceivable philosophical challenge to Christianity, from "Agnosticism" to "Zen Buddhism." It also summarizes the key points regarding oft-challenged Christian doctrines and beliefs ("Adam, Historicity of," "Virgin Birth of Christ"). Each article is cleanly written and clearly organized. Indeed, Geisler's greatest talent is for logical thinking. Whether he is considering Jesus' view of the Bible or the tenets of Deism, he writes with confident assurance, so that no reader will feel lost. ~ Amazon.com
