Your lack of sword will surely not help:
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. Luke 22:36

Personal self-defense against getting killed by randoms is probably the context given Romans 13 and 1 Peter 2:13.
Romans 13 says, “Everyone must submit himself to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. 2Consequently, he who rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves.”

The hyper sinful dis-obedient Jews were told by God to submit to Babylon, and live, or resist and die.
“Do not listen to them; serve the king of Babylon, and live! Why should this city become a ruin?”

Don’t resist. Repent and believe.
Otherwise, Russia and China will see it as too monstrous opportunity NOT to attack. We will be toast.
“is probably” , but you are not sure. So do you own a weapon according to this scripture to protect you and yours against random acts of violence?
If anyone does not provide for his relatives, and
especially for his immediate family, he has
denied the faith and is worse than an unbeliever.
1 Timothy 5:8
Jews were told by God to submit to Babylon, and live, or resist and die. But God also helped the Jews defeat many of their enemies and battle.
We saw how well not resisting evil Godless authority did the Jews against the Nazis.
Better a death as those of Masadah than those of Dachau.
Blessed be the LORD my strength which teacheth my hands to war, and my fingers to fight: Psalm 144:1
