Pastor Jeff Johnson is the pastor of Grace Immanuel Reformed Baptist Church in Grand Rapids, Michigan. He joined Paul on WMUZ in Detroit to talk about his book, "Taming the Fingers: Heavenly Wisdom for Social Media," published by Reformation Heritage Books (www.heritagebooks.org).

While social media has many benefits, it has often served as a breeding ground for divisiveness and hostility. Hidden behind our screens, we are often tempted to type things we would never say aloud. In this helpful book, Jeff Johnson encourages us to tame our fingers with wisdom from the Proverbs. He organizes these principles under five guiding questions that can help us cultivate heavenly wisdom in our use of social media.
