Military Service

My idea for a question on this topic:
What does the Bible teach about whether believers should serve in the military?

Matthew 5

v39

But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.

I know believers who serve in the military because they think that's what the Lord wants them to do. However, right now I don't think that believers should do that, according to what the Bible says. We're supposed to be in the Lord's military, bond servants to Him and not to men, saving mens' lives and not destroying them. We're not supposed to be "servants" of men, bound to people like slaves, if we can help it. He said if we could be made free, that we should be. In the military, for example, if they tell you not to go to Church on Sunday morning, then you can't go to Church on Sunday morning. What if that's what the Lord wants you to do?

Swearing by an oath is required to join the military, but the Bible teaches not to swear by any oath. Most importantly, the Bible talks over and over again about how we must be gentle to everyone, harmless as doves, not working ill to our neighbors, doing violence to no person, not being fighters, not being strikers, not taking up the sword, etc., etc. The military definitely uses violence, injuring and killing other people. That is the military's line of business, in order to serve and protect this country. But, in my opinion, that is not compatible with the believer's line of business.
