This book serves two purposes--to honor the apologist and author Dr. Frank Turek and, in the spirit of his ministry, present reasoned responses to challenges currently facing the church. Every year, for more than one decade, Dr. Turek has hosted the Cross Examined Instructors Academy (CIA) through his Cross Examined Ministries, wherein he leads a group of professors and apologists as they teach and train others in the field of apologetics. Several rising stars within the apologetics community began their ministries because of Dr. Turek and the CIA. The authors of this book were chosen from this ever-widening pool of CIA attendees, past and present, most of whom have gone on to academic instruction or their own successful apologetics ministries. Their contributions broadly address challenges from philosophy and science; challenges against Jesus and the Bible; and even challenges facing parents and the church. Many topics offer new approaches, while others reestablish existing responses, but all seek to provide answers to a skeptical world for the hope that rests within all Christians.
