Aye – escuse the pun.
Reminds me of the scene in “The Untouchables” where the character played by Sean Connery say “They bring a knife, you bring a gun, they put one of your guys in the hospital, you put one of theirs in the morgue.” Violence begets violence and he who lives by the sword dies by the sword.
What do we know of weaponry in scripture? It is Ep6 where the armour is salvation, truth, righteousness, Spirit and readiness that comes from the gospel of peace, not taking revenge, knowing that id for God to address.
Can’t help thinking about Thin Lizzy with the thought of readiness. Are you ready? http://www.youtube.com/watch?v=j6t6zhpDpPs
