When Thomas Aquinas addressed the best arguments against God in his masterwork, the Summa Theologica, he listed only two. The first was the problem of evil: How can God--who is perfectly good--exist alongside that which is against Him? His second: Is God needed to explain the world? Patrick Flynn presents the best arguments for God while also addressing the strongest objections. This book is destined to become the apologetic gold standard for defending classical theism against atheistic naturalism. Flynn identifies what is at stake and then provides cogent, accessible, yet potent defenses to counter those arguments that atheists routinely make to justify their claim that there is no God. Flynn defines commonly misconstrued terms and illustrates them with real-world examples. With sidebar definitions and detailed explanations, Flynn guides you in learning authentic reasons for your belief in God. He evaluates whether it's simpler to believe in God or not, and he provides numerous arguments from philosophy, science, and plain common sense. Flynn's in-depth analysis will give you the tools you need to share your belief in such a way that those who deny God's existence will have to defend their view. Also featured is an appendix with a dozen additional objections and bulletproof replies for the existence of God.
