Hey, I’ve got news for you. You’re going to face them at SOME point anyway. Cower in fear or stand and fight the good fight. I know what God’s Word says.
Then, by all means, join up with your fellows and act on your words. Set an example for me and others. Please report back once you get to the middle east. Heck, you don’t even have to take up arms. Transport some bibles to Saudi and try to win souls for Christ. (oh wait, the Catholic church does DO THAT behind the scenes... so you can join those brave folks).
