If my family is a gift from God and was put in my charge, I will answer for what happens to them. I will not watch them be slaughtered because of a vague argument over the 6th Commandment. God has His "people" and then all others. The Bible is for His people. This is and old argument over who will be saved and did Jesus come for the whole world? My common sense tells me that God will judge His people on what they did and believed and all others will be judged guilty because they didn't accept Jesus as their substitution. That means someone is guilty and will end up in Hell. They are NOT His people. The others, which did believe, are going to Heaven, no doubt about it. Their judgment will be on their works, but they will go to Heaven, even if they have the smell of smoke on their garment. As a Christian, I am saved and am forgiven of ALL sins, even the ones that I commit tomorrow. As long as I don't blatantly attack "the innocent",( and that is what we are discussing here), I haven't murdered. I do no relish the idea of killing, but I will if I must to keep the lives God has blessed me with. I understand the difference of opinion, but have already decided what I would do in these situations. I have heard the stories of Christians hiding in closets to keep from confronting intruders because they didn't want to take a hunting rifle and kill the intruders. They and their family were murdered so they wouldn't have to make that choice. I have made the choice in advance and am satisfied that Jesus would forgive me as he does every day for my many shortcomings. He is either my Savior, and stands for me, or it's all a lie. There is no sin bigger than another. If he can forgive me of lust and envy, He can forgive killing people that haven't raised a hand yet to me. Either way, I will defend my family and happily defend yours from evil. I know right when I see it and I certainly know wrong when it is right there in front of me. I have faith that I will be in Heaven because of my Trust, even if Sherman is on a Jury that finds me guilty and puts me to death. There are consequences for every belief and I will accept mine. If you bow to Allah, then they must accept theirs. There have been many names over the years that people called their god, but just as Baal worshipers died at the hand of a righteous man, so to will the moon god worshipers. They can die from my hand or the hand of the One coming on a white horse, but die they will.
We can argue over the details, but it won't change anything. I pray I'm never put in those circumstances, but I already know where I will stand if it comes. We would do better to argue why don't the Christians pack up and leave Somalia rather than stay to be slaughtered, but I know many can't, so you now see the desperation the Christians are put in. If a Somali pirate can get an AK, I bet I could also.
I say all of this because we cannot add one iota to our life span nor can we take it from anyone else. Leaving aside murder, if we fight for our existence and succeed, our relationship with the Lord is not changed. No more than when the Lord commanded the Israelites to slaughter the inhabitants of Canaan. It is the Lord who gives life, He who brings about victory in defending it, and He who allows the martrys of saints.
