Hearing about the disgusting and outrageous tragedy this morning at Pulse nightclub in Orlando, my heart sank, and I began to weep – 50 dead and 53 injured. This mass shooting is the deadliest in United States history.  The shooter has been identified as Omar Mir Seddique Mateen, and officials have identified it as a terrorist attack. Sitting here with my family, listening and watching the reports, I ask: How should Christians respond to this tragedy?
