Our beliefs on Jesus differ. A soldier fighting in defense of his country, is not fighting for his religious beliefs.
Being fairly new here, I haven't a clue to your beliefs on Jesus, but if you would like to share them, go ahead.
I think a soldier fighting for defense of his country is the same thing. He is fighting for what he believes in and he is willing to lay his life on the line for those beliefs. I don't really see any difference between fighting for those beliefs and a Christian willing to lay down their life for theirs. Just my take on it.
What is a country? Invisible lines on a map drawn by others that symbolize the boundaries of a patch of earth even birds disregard because it isn't 'real?'
