Why Eric Metaxas wrote "Letter to the American Church" - and Matt Staver

The apostle Paul wrote letters to the churches of his day. Jesus wrote 7 letters to 7 churches in Revelation. What might a letter to the modern American church look like? Eric Metaxas tackles that question in his best-selling popular book "Letter to the American Church." Mark talks to Eric about that this week, as well as another expert on the spiritual state of America: Matt Staver. Brought to you by Mark Taylor and the Sky High Podcast Network.
