The killer at VA Tech was diagnosed with selective mutism in high school. In certain situations he was supposedly unable to communicate, like public speaking. Sounds like some Christians suffer from selective mutism, too – they are “unable” to speak for Christ in any kind of social setting. It’s not that we are by temperament quiet – anything but. We still haven’t settled the issue that men cannot believe that which they have not heard, and they cannot hear unless someone tell them.
