What If Christianity Is True?

“Christianity is a statement which, if false, is of no importance, and if true, is of infinite importance. The one thing it cannot be is moderately important.”

Download the free ebook, “What if Christianity is True?” This ebook gives compelling evidence for belief in Jesus Christ and the Christian worldview. This booklet is useful for answering some of the most pressing questions that students are faced with on college campuses. If you are a student, download this resource to help you get the answers to answer the doubts you hear every day. If you are a parent, this ebook can help you prepare your child before they go to college or answer the challenges he or she will receive at their university.

In the pages of this booklet you will get a taste of a complete apologetic for Christianity and what we do on campuses all over the world. This resource, inspired by I Don’t Have Enough Faith to Be an Atheist (Crossway, 2004) by Norman Geisler and Frank Turek, as well as the classical apologetics taught at Southern Evangelical Seminary (, includes summaries of each premise in a 12-step argument for the truthfulness of Christianity. It is our desire that you will study the arguments, investigate the endnotes and recommended resources, and begin your journey of knowing why Christianity is true so that you can either put your trust in Jesus Christ for the first time or be equipped to communicate to others your convictions in a winsome and respectful way (1 Pet. 3:15; Jude 3). There is no room for blind faith in the war of ideas for your mind (2 Cor. 10:5).
