Christ Himself told His people to arm themselves.
Luke 22:35-38
- "He said to them, When I sent you forth without a money bag or a sack or sandals, were you in need of anything? No, nothing, they replied.
- He said to them, But now one who has a money bag should take it, and likewise a sack, and one who does not have a sword should sell his cloak and buy one."
- For I tell you that this scripture must be fulfilled in me, namely, He was counted among the wicked; and indeed what is written about me is coming to fulfillment.
- Then they said, Lord, look, there are two swords here. But he replied, It is enough!
What is a firearm but today's equivalent of a sword?
