Do you think that will stop them? How well financed are they? Who's financing them? Who's on their side? (Evil) This is a war of attrition. They're going to keep going to see how many they can simply wear down and get to renounce their faith.
Good people of faith know this story well, it's been written about. We know how it ends, we know who wins, that still doesn't mean evil stops and simply gives up. Evil wants to take as many of us as they can with them. Evil is definitely on the march.
Stop bellyaching and grow a pair.
