Prayer will not stop the killing, only action will. Even the act of teaching and talking to the enemy, but not hiding on ones knees and asking some invisible force to act in place of you.
That is just cowardly and ineffective.

I did not hesitate to protect my loved one when confronted with evil. I used the butt but was quite ready to have pulled the trigger. He blinked, I did not.
For decades devout people who did pray were not save against the evil being carried out.
I spent year trying bring about a peace. Force was what eventually brought and end to the fighting. People on all sides are still struggling to prevent a repeat, not always effective but better than the total chaos and violence being unleashed.
