Let me tell you why.
a. Because legally, I can.
b. The world is extremely unstable and unsafe right now.
c. Because, I believe that The Word Of God not only allows for such things, but even endorses it's use for the preservation of life.
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.Legally, as spelled out in the 2nd Amendment to the Constitution, you are allowed to bear arms. The left will tell you this means that only a government regulated militia is allowed to be armed and only then can they have muskets. Using this argument the 1st Amendment right of free speech only applies to telegrams sent by the pony express. As if somehow the first words are a qualifier for the 2nd half of the Amendment.
There is no qualification for the right to bear arms. It's just a right...to own a gun. That's it. Why do you have a "right" to this? It's simple. The founding fathers knew that a day would come when someone would take office and go after the freedoms that, according to them, are God-given. And without the ability to defend such liberties they would vanish from the face of the earth.
It would be like if you were given a priceless gem, but were not given a way to secure it. It'd be like if the Louvre kept the Mona Lisa out on the front lawn at night with just a street light and a 80 year old security guard with a whistle.
The world is sick and evil and getting worse every day. The Bible is clear that life is sacred. We only get nine chapters into The Bible before God establishes the death penalty, and the precedent for righteous people carrying a gun, or sword, or club.
Genesis 9:6 "Whoever sheds human blood, by humans shall their blood be shed; for in the image of God has God made mankind.
Bam! Black and white, even before the law is established He lays out the ultimate punishment first and foremost. You CANNOT take life, Which HE created in HIS own image. To do so is to forfeit your right to your own life.
So, stopping a murderer with a personal weapon, as long as you are in the right, and are absolutely sure that lethal force is necessary in order to stop them.. Go for it, with God's blessing! Protect life.. within the law.
But what if the person is simply breaking into your neighbor's house to rob them...
Look at what Jesus said in the Garden Of Gethsemane..
Luke 22:49-53 (NAS) 49 And when those who were around Him saw what was going to happen, they said, "Lord, shall we strike with the sword?" 50 And a certain one of them struck the slave of the high priest and cut off his right ear. 51 But Jesus answered and said, "Stop! No more of this." And He touched his ear and healed him. 52 And Jesus said to the chief priests and officers of the temple and elders who had come against Him, "Have you come out with swords and clubs as against a robber? 53 "While I was with you daily in the temple, you did not lay hands on Me; but this hour and the power of darkness are yours."
This scripture does two things. It tells us that there is a time when NOT to use a gun. To advance the Kingdom.. Never! We don't place any trust in this gun. This gun is powerless if it wasn't for our Heavenly Father, and with that we gladly lay down our guns when it comes to heavenly pursuits. Basically that means when the time comes for us to become persecuted by the State, we will not fight back. Because you can have our body. It's worthless to us anyway.
The other thing in this scripture is when Jesus says "Have you come out with swords and clubs as against a robber?" He didn't say ...as you people do against a robber. He didn't qualify it. He said it like it is. Like it was obvious. If a robber is doing his thing, you don't stand there like a stump, you protect life, limb and even possessions, if not for yourself, especially your neighbor!
There are a ton of verses in scripture about the preservation of life, through all kinds of means. This does not mean that everyone is supposed to carry a gun. Carrying a gun is a HUGE responsibility. People need to be prepared and trained. The Old Testament talks a lot about having hands trained for war, and being proficient with the sword. And having a firearm at your side is not a thing to take lightly.
But being a Christian does not disqualify you in the active participation of being a citizen in a world that is less than civil. And all that entails.
