Luke 22:36 - Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
While there are many considerations and many demands on our time and assets, Jesus would tell us that arming ourselves with the best weapons available in our time is a part of being a good follower of His Word.
And they said, Lord, behold, here are two swords. And he said unto them, It is enough.
Jesus would also counsel moderation - balancing that need against other needs rather than strapping on dozens of swords (firearms) per person.
I've seen these versed used for pro-gun purposes. If I read the above verse in that context, then how could two swords be enough for the eleven disciples? Just asking.
