Although Ravi Zacharias is a fine apologist, I cannot agree that he is the best philosophical apologist in the world, as a previous reviewer stated. Many of his arguments are not even strictly rational ones, but ones that appeal to the intuition and the emotion, and other subjective aspects of thinking. In contrast I submit that the best living apologist is probably Vincent Cheung. His strictly rational and biblical approach is unrivaled and invincible. I recommend reading his PRESUPPOSITIONAL CONFRONTATIONS and ULTIMATE QUESTIONS, available from his web site. Also, try Bahnsen's ALWAYS READY, available here at Christianbook.com.
