When did the followers of Christ, the original peace maker, suddenly get the idea that they should be warriors? This is insane! Jesus was the furthest thing from a fighter, warrior or soldier of any kind.
He came to bring peace not to make war. Jesus came to this world to enlighten us and to save us. There is no battle here other than the one in our own mind. What could it be that we are fighting for when our Father in heaven is all knowing and all powerful? Any fight under these circumstances would be terribly one sided. This is especially true since the Son of man told us specifically that He will do whatever we ask as long as it glorifies the Father.
The only time that Jesus ever mentioned anything to the contrary was to exemplify the inevitable transformation that would take place in the hearts of man. He would cut from us the worldly things and bless us with Spirit. Love would reign and the old would be left behind. It was to free us from all these worldly constraints and make us available for God.
