I agree a Christian should always seek loving and peaceful resolutions to conflicts. We should not antagonize others into conflict either…but we cannot shrink from physical violence when it is necessary to protect other human beings I think of Hitler, sex trafficking, drug trafficking, physical abuse… I was a police officer in SoCal for 30 years. I agree with your statement that no officer or soldier wakes up with the intent to harm or kill anyone….I know that none of the men and women I worked with had that on their to-do list! As a believer in Christ, when I began my career, I asked God how I should view the people I would encounter. He told me to remember they are His image bearers and I should talk to and treat them accordingly and if physical contact happend it was their behavior that determined the level of force imposed upon them. I share this to say Christians must stand for the truth of the gospel and part of it is protecting the innocent from harm and abuse…how can we justify not stepping in to prevent harm?
