This is Greg Koukl. He is the founder of Stand to Reason, an organization committed to a clear articulation and defense of the Christian worldview. He is a crisp thinker and a good communicator.
Here is 5.5 minutes of informative video on what the best argument against theism may be. One great snippet from the video is that atheists don’t ague to much on this point because they “think” it is settled. They believe they are the majority position when in actuality 98% of the WORLD population is theistic. Less than 2% really holds that there is no God. Interesting. Check out the video and learn about defending your faith.
Thanks Greg for being a stand up guy. I’d like to shake your hand someday.
