Who We Are

The People of IRR and What We Are All About

The Institute for Religious Research (IRR) is a nondenominational, evangelical Christian ministry of apologetics and discernment. It was founded by Roger Hansen, a Christian businessman who serves still today as Chairman of the Board of Directors. IRR, which was originally known as Gospel Truths Ministries, was established as a nonprofit, 501(c)(3) organization in 1986 and officially changed its name in 1989. From that time until his passing in November 2007, Luke P. Wilson was IRR’s Executive Director. Throughout this entire period Luke worked alongside Joel Groat, who continues as IRR’s Director of Ministries.  In September 2008, Rob Bowman, a veteran of nearly twenty-five years in apologetics ministry, joined IRR and serves as its Executive Director.

We desire to promote — in a thoughtful and gracious manner — the exclusive claims of Jesus Christ as Savior and Lord, as revealed in the Bible. For more information about what we believe, please read our Statement of Faith.

For ten years Rob taught graduate courses in apologetics, biblical studies, and religion at Luther Rice University (1994-99) and Biola University (2001-2005). He has also worked with other apologetics and discernment ministries, most notably the Christian Research Institute (1984-91), the Atlanta Christian Apologetics Project (1994-99), and Watchman Fellowship in Alabama (1999-2000). Rob has spoken at over a hundred churches and at some three dozen conferences and debates. He has five years of experience hosting call-in radio talk shows focusing on apologetics, including the nationally famous Bible Answer Man show.

Rob Bowman earned the M.A. in Biblical Studies and Theology from Fuller Theological Seminary, did doctoral studies in Christian Apologetics at Westminster Theological Seminary, and earned his Ph.D. in Biblical Studies at South African Theological Seminary. He is the author of roughly 60 articles (e.g., in the Journal of the Evangelical Theological Society, Review of Biblical Literature, Christian Research JournalMoody MonthlyPastoral Renewal, Mission Frontiers, and Journal of Evangelism and Missions) and 13 books pertaining to apologetics, religion, and biblical theology, including two winners of the Gold Medallion Award, An Unchanging Faith in a Changing World (1997) and Faith Has Its Reasons (2001; 2d ed., 2006). His most recent books are Putting Jesus in His Place: The Case for the Deity of Christ (co-authored with Ed Komoszewski, 2007), which received numerous endorsements from such scholars as Ravi Zacharias and Richard Bauckham, and What Mormons Believe (2012).
