If a brother or sister has nothing to wear and has no food for the day, and one of you says to them, “Go in peace, keep warm, and eat well,” but you do not give them the necessities of the body, what good is it? So also faith of itself, if it does not have works, is dead. Indeed someone may say, “You have faith and I have works.” Demonstrate your faith to me without works, and I will demonstrate my faith to you from my works. -James 2:15-18 NAB
There are times and places where being a competently-armed greatly enhances the chances that evil people will allow you to "Go in peace..."
Might one of "the necessities of the body" also include the means to protect one's self and those who are under your protection?
