Twelve Points That Show Christianity is True: A Handbook on Defending the Christian Faith

Twelve Points That Show Christianity Is True presents a clear and carefully reasoned case for the truth of the Christian faith, grounded in logic, philosophy, and historical evidence. Norman Geisler leads readers through a step by step argument that begins with a foundational claim: truth exists.

If truth exists, then reality is knowable and meaningful. Worldviews that deny objective truth undermine themselves, since the claim that "truth does not exist" must itself be either true or false. From this starting point, Geisler demonstrates that the existence of truth points beyond the material world to the existence of a theistic God. This God is not an impersonal force or abstract principle, but a personal, rational, and infinite Creator who grounds truth itself.

Once the existence of a theistic God is established, the possibility of miracles cannot be dismissed. If God created the universe, then He is not limited by natural laws. This shifts the discussion from philosophy to history. Geisler then examines the New Testament, arguing that it is a reliable collection of historical documents that accurately records the life and teachings of Jesus.

The historical record shows that Jesus claimed to be God and supported that claim through a convergence of compelling evidence. This includes His sinless and miraculous life, His fulfillment of specific prophecies written centuries before His birth, and most importantly, His bodily resurrection from the dead. Taken together, these lines of evidence form a cumulative case that Jesus did not merely assert divinity but demonstrated it.

If Jesus truly is God, and God cannot err, then Jesus' view of Scripture carries ultimate authority. Since Jesus affirmed the Bible as the Word of God, the logical conclusion is that the Scriptures are trustworthy in all that they teach. Any worldview or belief system that contradicts God's Word is therefore false.

This second edition continues Geisler's legacy of rigorous reasoning and accessible apologetics, equipping readers to understand, defend, and confidently present the rational case for Christianity.
