What kind of faith needs guns in its defense?

So this is what Jesus meant when he said this? “But now, he that hath a purse, let him take it and likewise his pack; and he that hath no sword, let him sell his garment and buy one.” Luke 22:36.

I find this very disturbing. But I can imagine that if I were a Christian I’d find it even more disturbing. A politician tells a Christian talk radio show this:

“[Guns] are used to defend our property and our families and our faith and our freedom, and they are absolutely essential to living the way God intended for us to live.”
