If you don’t know about Jim Wallace take the time to read a detailed look at his background: https://en.wikipedia.org/wiki/J._Warner_Wallace
J. Warner Wallace is a cold-case homicide detective, adjunct professor of apologetics at Biola University, Christian case maker and author. J. Warner was a conscientious and vocal atheist through his undergraduate and graduate work in Design and Architecture (CSULB and UCLA); he always considered himself to be an “evidentialist”. His experience in law enforcement only served to strengthen his conviction that truth is tied directly to evidence. But at the age of thirty-five, J. Warner took a serious and expansive look at the evidence for the Christian Worldview and determined that Christianity was demonstrably true. After becoming a Christ follower in 1996, Jim continued to take an evidential approach to truth as he examined the Christian worldview. He eventually earned a Master’s Degree in Theological Studies from Golden Gate Baptist Theological Seminary.
Jim also has his own website: http://coldcasechristianity.com/
Jim has produced some of the best Christian Apologetic videos that I have seen. If you haven’t viewed them I would strongly encourage you to do so. His books are also excellent.
Here are a sampling of his many videos as found on YouTube: (you’re in for a treat)
