Is there a God? Is Christian rational? Do Science and Scripture agree? Does Christianity really differ from other world religions? These are not only the questions many Teen Challenge students wonder about but also some of the chapter titles of this book. If you or your students have been asking similar questions about Christianity, you need to know that Christian faith and reason are compatible and Paul E. Little explains how. Know Why You Believe examines the tough questions surrounding Christianity and helps you to be certain of your faith.
