Okay, 'tis as I thought. You used the verse out of context. You quoted part of Luke 22:36. This is the last supper chapter, when Jesus knew Judas was about to betray him, that He was taking his last food and drink before entering the Kingdom. He was about to leave his disciples, and they were to enter into a new phase of service to Him. They would now have to face hunger and poverty and danger, and it would be necessary for them to make provision. They should now take a money bag, a knapsack or lunch box, and the absence of a sword they should sell their clothes and buy one. What did our Savior mean when He told them to buy a sword? It is clear he did not intend for them to use the sword as an offensive weapon against other people. That would be in violation of His teachings, such as:
"My Kingdom is not of this world. If My Kingdom were of this world, My servants would fight."
"All who take the sword will perish by the sword."
"Love your enemies."
"Whoever slaps you on your right cheek, turn the other to him also."
I don't mean to say I know what He meant. Some say he referred to the protection of an ordered gov't, concerning that in Romans 13:4 about the power of a magistrate.
Matthew 5:39 seems to rule out the use of the sword event or defensive purposes.
The next verse, Luke 22:37, explains it further: Soon he would be departing from them according to propehecy. The things concerning Him had "an end." That is, His earthly ministry would come to a close by his being numbered with the transgressors.
22:38 - The disciples completely misunderstood Him. They brought forth two swords, implying that these would be sufficient for any problems ahead. They apparently thought they could foil the attempt by His enemies to slay Him, by using the swords. THATWAS THE FARTHEREST THING FROM HIS MIND, as he certainly knew what was coming.
You cannot use that verse in defense of your rights--rights that were given to you by the 2nd Amendment. As I said, I belive in the Amendment, but I don't give it more credence than it has on its own. It is what it is and that's all it is.
