Hi Mike :
Let me first start with this and that this is what I feel in my heart we are to do. We are no longer living under the law of the Old Testement so I would rule out the eye for an eye. I do believe that we should as much as possible turn the other cheek. If it is possible you just remove yourself from any areas of conflict. Remember always that God is Love ! Did you see Jesus throwing a punch or did He just remove Himself ? He removed Himself and then went and prayed for those that had offended Him ! This is our example to live here on earth in these days ! There will be more accomplished through prayer than with confrontation of any kind ! Again, I say this from my heart and it has worked so far for me in my life !
God Bless you Mike and read the examples in the New Testement where Jesus delivered us from the Law !
