Burson and Walls have written an insightful, timely book here which draws upon the thoughts and ideas of two men, whom they rightly proclaim as the most influencial Christian apologists of our century. This book should be widely read by Christians everywhere, but it most likely won't be, because interest in theology and apologetics doesn't seem to be exactly thriving these days. Still, to those who feel that theology matters, this book is chock full of useful information. Schaeffer and Lewis are shown here to have held many different views towards issues such as predestination, the atonement, and divine revelation, but one thing they most certainly did agree upon: the absolute necessity for Christians to engage their culture with the liberating truths of their Master, Jesus. Burson and Walls make this clear, and glean some very practical lessons for the rest of us to take and ponder while continuing to "bear the Light" in the world as these two giants did. This book reveals the genius, passion and courage of both men, and I for one hope and pray that it will encourage believers everywhere to follow in their footsteps.
