Should a Christian fight in the military?

Interviewer: Speaking of fighting and all, should a Christian be in the military?
God: The primary job of a soldier is to fight wars. Why would a Christian want to fight wars?
Interviewer: I don’t know. Perhaps it is just a job. Or perhaps someone feels there is a genuine threat to his family and country so he joins up to defend them.
God: Putting the genuine need to defend your family aside, a soldier’s job is to be the muscle behind a country’s government. The governments of the world are largely just the instruments of vested interests, so why would a Christian want to go off and fight wars for unrighteous governments?
Interviewer: So You are saying no?
God: What is your conclusion?
Interviewer: Well, some of our governments certainly like to invoke Your name and tell people they are fighting for “God and country.”
God: I don’t recall them asking Me before they brought Me into their fights. Governments and leaders have always proclaimed that I was fighting on their side. That way they dupe the people into thinking that if I am on their side, for sure they are going to win. But I am not interested in governments and countries gaining more land and booty at the expense of others, which is basically what wars have always been fought over. Wars are for economic gain, and seldom has there ever been a righteous war. And some of the so-called religious wars have been the worst.
Interviewer: But getting back to the defense issue, didn’t even Saint Augustine9 say that war could be just if a war is fought for moral purposes and with moral means? He claimed the two basic just causes10 of war are self-defense against criminal attack and aiding the victim of such an attack.
God: Self-defense and coming to the aid of the weak is one thing. Yes, for goodness sake do that. But bear in mind that in many cases, who is to say which side is criminal and which side is not? From all I see, there are a lot of criminals on both sides. So why would a Christian want to get himself into the middle of all that?
Interviewer: So as a Christian, what duty do I owe my country’s government?
God: You are, as the Bible says, to live as peaceably as possible in your community, giving no offense so that you may not be reproached. Live according to the laws of the land.
Interviewer: So I am to be a good law-abiding citizen.
God: Claiming God said you didn’t have to obey the law hasn’t been very effective as a legal defense. Besides, I told you to live according to the laws of the land.
Interviewer: Jesus was executed as a criminal.
God: He was unjustly and falsely accused and sentenced by a kangaroo court.
Interviewer: But even in today’s legal system the common belief is that it doesn’t matter if you’re guilty or innocent. What matters is how good your lawyer is.
God: But you should avoid even ending up in court.
Interviewer: Well, a lot of Your people have ended up in court, and have gotten the raw end of “justice.”
God: That is true. If a Christian is dragged into court on trumped-up charges, that is another thing. But if he is guilty of real criminal offense, then he has to pay the price. The laws of the land are there for your protection. If you follow them, you can claim the law’s protection. If you don’t, then you are on shaky ground.
