I agree with you Berlinda. It is no good to fight in the worldly armies, at least not in the time era that we find ourselves in.
It reminds me of my friend's grandpa. He has passed now, but he was a soldier during WW2, even saw the body strewn beaches of Normandy the day after D-Day. Was torpedoed twice by nazis, and his brothers served in the army of the infamous Patton. He very much wanted to fight in WW2 and he said he would do it again without hesitation. Back in the heyday of the Iraq War my friend asked him an interesting question of; if he were a young man like unto us, if he would fight in these wars? He told my friend, his grandson, no. His reasoning was that all the wars today are full of lies.
He was quite right.
Biblically, you do actually have much scripture to back up not fighting carnally any of these wars. From the Gospel examples of Jesus rebuking Peter for slicing the ear of the guard, to Jesus rebuking John for asking if he should call down fire like Elijah, to my favorite verse in Ephesians. Make no mistake though, we are fighting a war, but it is not a war against flesh and blood, and it cannot be fought by worldly material means.
