In a discussion at Evidence 4 Faith's March 25, 2012 podcast, Keith Kendrix had several guests in the studio who attended the rally. I found it to be very interesting, and suggest that it is well worth an hour of your time. You can click on the link above and go to the "Podcasts" link, or download the MP3 here.
But wait, there's more! If you act now, I will include, absolutely free, Greg Koukl's commentary on the use (or the lack thereof) of reason at the rally. This slightly edited excerpt (below) is from the Stand to Reason podcast from March 25, 2012. After you hear the clip, I suggest that you download and listen to the entire 2-1/2 hour podcast. There are some interesting calls, and the third hour is an interview with Tom Gilson, an editor of True Reason: Christian Responses to the Challenge of Atheism. This is a low-cost e-book. (Don't have a reader? No worries, you can download free software from Amazon to take care of that problem.)
Christians, we do not need to be intimidated by atheistic bluster and bullying. Reason comes from God, after all. Some of the greatest scientists and intellectuals of all time have been Bible-believers. It's time to stop surrendering to the loud, illogical minority and reclaim our ground. And yes, Christians need to read True Reason as well. And show that we are capable of using true reason.
