Was the Civil War wrong? Was it sinful for union soldiers to go to war and die to free men and women they didn't even know?
Was it sinful to fight the Nazi's?
Was it sinful to fight a cold war, that got pretty hot in various parts of the world, in order to crush communism?
Come on, get some perspective. There are times that we must stand and fight. When Jesus said to turn the other cheek He did not say turn and run away. You stand your ground in the face of evil. The Nazi's were evil. The communists were evil. The muslims are evil.
War is indeed sinful.
The Civil War was sinful on both sides. But look at the atrocities on both sides. How can you call any of them moral. The Nazis were wrong and therefore we had to take the measures that we did. But I challenge anyone here to call the firebombing of Dresden moral. Come on, anyone? Is there an answer to this?
Jesus does allow us the right for self protection to a point. But only to a point. The high priest’s ear was restored because Jesus didn’t consider even His own death to be justification for that level of violence.
We may protect one’s self, but not aggressively pursue world domination, according to Scripture. Jesus admonishes us to allow our enemies to pluck our beards. I do not detect that except with derision amongst the fundamentalists. I quoted this recently on a post and had the post replied to with the general thought that I was a masochist and that I enjoyed being a martyr.
WF, the answer to all your questions is Yes.
