Here's a question: what if the government takes your guns? What if it specifically targets God's people as being too dangerous to own even swords or knives? As a proponent of the right to keep and bear arms, I know that such a thing might happen, and I'm NOT a fan. As it turns out, this has happened before:
"Now there was no blacksmith to be found throughout all the land of Israel, for the Philistines said, “Lest the Hebrews make swords or spears.” But all the Israelites would go down to the Philistines to sharpen each man’s plowshare, his mattock, his ax, and his sickle; and the charge for a sharpening was a 7 pim for the plowshares, the mattocks, the forks, and the axes, and to set the points of the goads." (1 Sam 13:19-21)
The point being that we shouldn't be hugely worried. God's in control. Converting people to Christ is our best and only true weapon.
"For the entire Law is fulfilled in in this one word: "You shall love your neighbor as yourself."—Gal 5:14
