The sword is one great tool that is used in protecting lives but most times, people use it in taking lives rather. In the past, people used swords in taking territories and spoiling goods. Today, the sword is just a mere weapon that people use to steal, be it property or other.
Those who live by the sword will die by the sword, because they picked it up (Matthew 26:52). When you have a sword, the message you are sending out to observers is that you are a killer, or at least a swordsman who fights. So, people who take up the sword never live pleasant lives; their life is full of physical battles and wars.
But I want to recommend a certain sword, which when you use, brings peace. This sword is the Sword of the Spirit, which is the word of God. In Hebrews 4:12, this sword is life (i.e. gives or brings about life), it is powerful and also sharper than any double-edged sword on earth. This sword is so unique it cuts about anything.
Some swords boast of piercing through organs without killing a person but this Sword of the Spirit is able to divide/separate the bone from the marrow. If you know how intertwined the bone and marrow is, you would know that this is an impossible feat for man. But like as Matthew 19:26 says, all things are impossible for man but not with God.
Instead of taking up any sword to protect your life, which could even lead to your imprisonment if found on you, I recommend the Sword of the Spirit. Take up the Bible and study it because with it, you will be able to defeat the kingdom of darkness in your life and family (Ephesians 6:12-18).
If you must know, we are in a war here; the kingdom of light is fighting against the kingdom of darkness and taking up the Bible enrolls you into the kingdom of light. Being in the kingdom of light is much safer than any other kingdom because light is greater than darkness.
In the time when the Beast reigns, that is when the patience of many will be tested (Revelation 13:10). Those who cannot humble themselves will lose patience and fight back with all they can, but they will be defeated or at least killed. Those who wait on the word of God and look into it will be satisfied with their souls because they have plenty. I pray you choose to live by the word of God. God bless you.
