Dear brother Nash,
I agree with you on that account, that if someone is doing violence to you, especially as a witness of Jesus, we should not attempt to hurt them bodily.
However, if someone broke into my home, and was after my wife or daughter, they have put themselves in danger of bodily harm. I hope I never have to do this. I give my body to be burned, however, I won't give someone else the authority to rape or murder someone in my family or anyone else for that matter.
Matthew 24:43 "But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up."
Luke 22:36 "Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one."
Please notice the message to Peter after he used his sword to defend Christ:
Matthew 26:52 "Then said Jesus unto him, Put up again thy sword into his place: for all they that take the sword shall perish with the sword."
Jesus doesn't need physical defending by man's device, but people do need defence.
Please read Romans 13:1-4:
"Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God. Whosoever therefore resisteth the power, resisteth the ordinance of God: and they that resist shall receive to themselves damnation. For rulers are not a terror to good works, but to the evil. Wilt thou then not be afraid of the power? do that which is good, and thou shalt have praise of the same: For he is the minister of God to thee for good. But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil."
