I looked this verse up and did some research on it after I came across it in Sunday school a few months ago, and here is what I found out. We hear "sell your cloak and buy a sword" and think that it equates to everyone. We are however taking out of context. He was speaking directly to TWO of his disciples to go out and buy a sword. He did this to fulfill a prophecy from the Old Testament, in that the Messiah would lead an armed rebellion of sorts. The Romans considered a group with TWO swords an armed rebellion, and this is the reason why he told them to go out and get the swords.
It sounds awesome, and I'm sure that Jesus would support gun-ownership, but I think that we take that out of the context in which it was written. Spiritually...I'll leave that up to each person.
FWIW
