How can anyone claim to be a Christian and support war? That is an impossibility. Being a Christian means you subscribe to the teachings of Christ, who was completely against the whole concept of war. In every thing he said in the Bible, he never once mentioned that killing others was an ok thing to do.
He DID however, speak of taking care of the poor, sick, and imprisoned populations. He never said we are to judge these people, but tend to their needs. I challenge anyone who believes wars are a necessity in the world to prove me wrong on either of these points.
So the next time you tell someone you are a Christian while supporting or participating in war, remember you are on your way to Hell according to the teachings of Jesus. It’s really that simple.
