Dr. Norman Geisler, PhD, was a prolific author, veteran professor, speaker, lecturer, traveler, philosopher, apologist, evangelist, and theologian. To those who ask, “Who is Norm Geisler?” some have suggested, “If you can imagine a cross between Thomas Aquinas and Billy Graham, you’re not too far off.” A mentor to countless apologists and theologians, several consider him to be the grandfather of classical, evangelical Christian apologetics–a wide-ranging, holistic apologetic that would encompass foundational matters like knowing truth about reality, to knowing God exists by reasoning from effects to their causes, to the historical trustworthiness of the four gospel accounts, to the fact of the bodily resurrection of Jesus from the dead, to the full deity and humanity of Jesus Christ, to Jesus’s view of the Bible as without error. True to his middle name, Norm was a lion; he was certainly one of the greatest defenders of the reliability, inspiration, infallibility, and inerrancy of the Bible in the late 20th and early 21st centuries.

Norm authored or co-authored over 100 books and hundreds of articles. He taught theology, philosophy, and classical Christian apologetics on the undergraduate and graduate level for over 50 years and served as a professor at some of the finest seminaries in the United States, including Trinity Evangelical Seminary, Dallas Theological Seminary, Veritas International University, and Southern Evangelical Seminary.
