Christian Case-making with J. Warner Wallace and Why I believe in Christ

On this Freedom Friday, we discussed the importance of knowing why you are a follower of Christ. We must know the God we serve and why we serve Him, or else risk living a life in vain. We turned to the phone lines to hear from our listeners when we asked them, “What did you see that ultimately caused you to believe in Christ?” We then had J. Warner Wallace joins us to unpack Christian case-making and presents some thought-provoking points about how to approach evangelism. J. Warner Wallace is a Dateline featured cold-case homicide detective, national speaker, podcast host, and best-selling author. He also serves as a Senior Fellow at the Colson Center for Christian Worldview. He is an adjunct professor of apologetics at Talbot School of Theology, Gateway Seminary, and Southern Evangelical Seminary. He has also authored several books, including “Cold-Case Christianity.” Shaunti Feldhahn also joined us to talk about the importance of mental health. Shaunti is a best-selling author, podcaster, blogger, and popular speaker. She was formerly an analyst on Wall Street and now applies her analytical skills to investigating life-changing truths about relationships at home and in the workplace. She has also authored several books, including “When Hurting People Come to Church: How People of Faith Can Help Solve the Mental Health Crisis.” You can hear the highlights of today's program on the Karl and Crew Showcast.
