This comes up every once in awhile where someone posts the veres of Luke which says:
Luke 22:36
36 He said to them, “But now if you have a purse, take it, and also a bag; and if you don’t have a sword, sell your cloak and buy one.
This is the only Biblical scripture that anyone ever posts about this issue to do with weapons. I have come across someone who did their homework and the Bible has very many more scriptures to do with the carrying and use of weapons. If read carefully and some critical thinking applied, it is very easy to see where it is speaking of not only owning weapons, but carrying them daily and even assault weapons. I found it very interesting and thought I'd share.
Enjoy.
