Apparently a lot of people here have never had a gun at their head! I have looked down the barrell of an AK47, 357 Magnum, and a Glock 9mm. Really a wierd sight to see and to experience. Human survival instint kicks in when your life or the lives of others is put on the line. Everyone reacts differently and I don't care if you are an Athiest or an Evangelist, FEAR kicks in! Obviously I am still here after those events and I won't say what happened to the other parties involved.
Have I taken life? I won't say! Would I take a life if put in a position of defense? Just don't be on the butt end of the gun or knife (weapon)!
Would I regret it if it happened? Absolutly! However, I am a Christian, I am a human and I am a man, dad, and former husband. Please don't test me on this issue. I will pray for you both before, during and after.
As for Matthew 26:50-53, you missed verse 54! There was a reason why Jesus stopped Peter! Read it in context.
Well I hope I haven't come across to hard, but.... Oh ya, how about the guy who walked into a church service and started shooting a few years back? Were they wrong in shooting him or should have they just started praying and wait for their turn?
Yes God is bigger than a gun or any situation we find ourselves in. However He gave us a gift call, "Comon Sinse".
