"And the light shineth in darkness, and the darkness comprehended it not."
The Christmas story tells of angels who sang of peace on earth to men of goodwill. As defined in Merriam-Webster's 11th Edition Collegiate Dictionary, "goodwill" means "a kindly feeling of approval and support: benevolent interest or concern." Hacking the heads off school children is definitely the opposite of that definition, as is butchering hostages and murderous shooting sprees.
The world is in very deep trouble today at the hands of a profound and expansive evil, radical Islam. Whether it's Al Qaeda, the Taliban, ISIS, or any other catchy name, this darkest of evils is not going to stop destroying until it is defeated. That battle is going to be a very tough, very lengthy undertaking--we're talking generations. It's going to take the resolve of many people of goodwill, from many nations, all of whom have the courage to fight this good fight.
God bless them, every one.
