What is a well meaning Christian to do?
Start patting people down at the door? Stop performing Annie? Just kidding... it would just downright un-Christian to do a weapons check at the door.
Our prayers and thoughts should be with this Church as it struggles with such a tragedy. I'd love to check tomorrow morning and find out that the shooter had some motivation like he was mad at his Dad or he wanted to rob the Church.
But if I had to guess this was a random act of hate and pain. There is no excuse, but as Christians consider persecution a good thing - we generally prefer to suffer for a particular cause (and not just randomly).
More as the story fleshes out....
I hate it...
