So for those who believe that Christians should own guns, would Christians be justified using a gun to protect themselves or their family under certain circumstances such as a robbery?
And would killing someone in extreme cases be justifiable?
I've not read all of this, but I stopped here to answer... Yes.
Men from the old testament days on have protected their family. Thou shall not kill is for "intended murder"... to go out and choose to take the life of someone else.
Read in the Bible and you will see that when someone attacked or came to harm, they not only defended themselves, they went back out and hunted them down and took their lands and cattle and everything.
I do not advocate that, but if someone believes they are to be the protector of their home, then by all means, they should be. It's no different than someone in the military being trained to defend the country or the post, or even the ship. When my husband is the officer of the watch, he carries a loaded weapon, and he is expected to be the defense between someone boarding that ship to do harm and the safety of his men.
It's no different for your home. I would suggest being trained with said weapon, having a license, and keeping your qualifacations up to date also. No wise man would get a weapon to keep without being able to use it and have someone take it from him and use it on him or his family.
But, yes... if someone is threatening the safety of your home, your family or you... you have a right to shoot them.
The Bible says that "But no one can enter the strong man's house and plunder his property unless he first binds the strong man, and then he will plunder his house." Mark 3:37. Why is that? Because the man of the house will fight them, and stop them. So be wise, be alert, and the one who stands between your families safety and their harm. Stand that line, by all means. God Bless.
Would I? Yes, I know I would. I'm from the hood. I have stayed awake many a night knowing I was the last defense between the world outside and my children. Its' been something I wrestled with time and time again... and then I knew. I would. The alternative would be to just "ALLOW" someone to come in, bind me, harm my kids or even kill them. I could not.
