The preacher made a good point today, I think.
Some Christians believe that we should not take up / carry weapons for self-defense, but Jesus, on the night of his betrayal, asked the group if they had any swords. They found two, and he said that was enough.
He wasn't going out to start a war, or even as an army, or he would have wanted all of them armed; but he did have enough weapons in the group to act as a deterrent to attack from ne'er-do-wells.
I don't know exactly what his intention was in asking for swords (self-defense, object-lesson of some sort, or what), but he obviously didn't have a problem with his followers walking around armed. He did however point out that an attitude anxious to use a weapon will likely lead to death.
