I am the Distinguished Professor of Philosophy at Talbot School of Theology, Biola University in La Mirada, California. I have four earned degrees: a B.S. in chemistry from the University of Missouri, a Th.M. in theology from Dallas Theological Seminary, an M. A. in philosophy from the University of California-Riverside, and a Ph.D. in philosophy from the University of Southern California.

During the course of my life, I have co-planted three churches, spoken and debated on over 175 college campuses around the country, and served with Campus Crusade for Christ for 10 years. For eight years, I served as a bioethicist for PersonaCare Nursing Homes, Inc. headquartered in Baltimore, Maryland.

My ideas have been covered by both popular religious and non-religious outlets, including the New Scientist and PBS’s “Closer to Truth,” Christianity Today and WORLD magazine. I have authored or co-authored 30 books, including Kingdom Triangle, Scaling the Secular City, Consciousness and the Existence of God, The Recalcitrant Imago Dei, Love Your God With All Your Mind, The God Question, and Body and Soul. I have also published over 70 articles in journals, which include Philosophy and Phenomenological Research, American Philosophical Quarterly, Australasian Journal of Philosophy, Metaphilosophy, Philosophia Christi, and Faith and Philosophy.
