It's a tragedy when four Americans on a yacht are killed by Somali pirates.
But when I heard about them being taken hostage, I thought, "Who would be crazy enough to sail by themselves into such a dangerous area, given all the other well-publicized hijackings in that part of the Indian Ocean?"
Then I learned that one of the couples had been distributing Bibles around the world. My suspicion is that they felt they were under God's protection.
Mistaken feeling, obviously.
However, I've little doubt that countless Christians are now saying, "It was God's will that they were killed." I also have little doubt that if they'd managed to survive, countless Christians would have said, "It was God's will that they were saved."
This is the nice thing about religious belief: it can't be proven wrong, because it's a belief. True believers can make reality into whatever they want it to be.
