“It is hard to overstate the impact that William Lane Craig has had for the cause of Christ. He is simply the finest Christian apologist of the last half century, and his academic work justifies ranking him among the top 1 percent of practicing philosophers in the Western world. Besides that, he is a winsome ambassador for Christ, an exceptional debater, and a man with the heart of an evangelist. I know him well and can say that he lives a life of integrity and lives out what he believes. I do not know of a single thinker who has done more to raise the bar of Christian scholarship in our generation than Craig. He is one of a kind and I thank God for his life and work.”

“On Guard is an excellent summation of how the Christian faith makes sense of the real world in which we all live. ‘Speaking the truth in love,’ once again William Lane Craig proves we don’t have to be abrasive to be persuasive.”

“William Lane Craig is arguably one of the finest Christian philosophers of our time. His knowledge and skill have placed him on platforms on every continent, engaging the most notable skeptics in dialogue and debate.”

“There is probably no greater defender of the Christian faith alive today than William Lane Craig. On Guard is Craig’s introduction to the wealth of information, logic, and evidence that powerfully point to the truth of our Christian beliefs. Read it to deepen your own faith and to embolden your confidence in sharing that faith with others.”

“In these pages, you’ll learn the most compelling arguments in favor of Christianity. Not only that, but you’ll also find out how to respond to the most popular objections to those arguments. You’ll discover that On Guard is solidly factual, winsomely personal, consistently practical, and ultimately convincing in its presentation of the case for Christianity.”
