I am saddened by the loss of life. I am particularly saddened by the loss of a father's life because the children that are left behind without that strong moral support, without that leadership are forever deprived of the means to understand a God that calls Himself, Father. It also creates a gulf of anger and a rift between those children and the King.
I am more bothered by cowardice. You see, I believe the enemy is a coward; that's why he has to use trickery and deception and ambush to destroy. If he were certain of his own abilities, he would make his presence known and his plans clear. Instead, he has to sneak up on us and like the cowardly cop killer in this story, take aim at us from a place in the woods, securely hidden from view and before we even have the chance to defend ourselves.
I suppose the best advice here is that we should always be aware of those dark spots in our lives, those wooded areas on the peripheral. Keep your eyes open, your ears alert and be prepared to fire back!
