Good question......Now I've read some of the comments and I thought I'd reply.
Someone said they may not do it..not just because it comes out of a book(bible). Others say their conscience is their guide. Cool.
Some say the Bible says not to kill. And of course it also talks about killing....Isreal's enemies. But if you examine it closly, it says not to murder. Murder is senseless killing.
Now many of us realizes jehovah Witnesses don't join the military. That's cool up to a point. Why? Because of the killing of the enemies. Yet the first few thousand years wars were made, especially to God's chosen people. God made war with His enemies. Yet King David followed God's rule on war.
Eye for an eye, life for a life.....the old text talked of civil law. Yet today we live under Grace.
Cornelius, Acts 10, was soldier. A centurion which as history says is a commander. He didn't give up his poisition. It says that he was a devout man and feard God.
So let's get this straight. jehovah witnesses have the right to refuse service from the military. It's in the Constitution. Yet the Bible says otherwise..........
In Romans 13:1-5 and 1Peter 2:13-15 states we should obay and submit to the governments. And what's more, if the governments do evil, God will judge them.
The Bible does not contradict itself. The Hebrew text,old testament, speaks under civil law....The Greek text,new testament, speaks of living under Grace.
I leave you with this thought..............
"knowing this first, that no prophecy of Scripture is of any private interpretation, for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit."(2Peter 1:20,21)
