How true can Christianity really be? In a culture where religion and "real life" often occur in completely different times and places, the question troubles many Christians. How can we give the reason for the hope that we have amid the many voices telling us that Christianity might be helpful or interesting, but not really "true" for anyone except Christians? Why should we ourselves bother with a religion so insubstantial that it is only legitimate within our own minds? People with real sins require a real savior, not merely inspiring stories and advice on how to live. As Though It Were Actually True provides Christians with an introduction to the age-old practice of apologetics--the rational defense of Christianity as objective truth. It explores some of the most important issues on which the Church finds itself in conflict with today's culture through a combination of critical reasoning, evidence, and the law written on our hearts. By providing a philosophical foundation that is reasonable, a historical foundation that is factual, and a theological foundation that is biblical, this book will help equip Christians to contend for their faith against the shallow and deceptive philosophies that seek to undermine it.
