John, that sounds a bit fatalistic to me. If you knew that your neighbour was severely abusing his wife and kids and storing unusually large quantities of ammonium nitrate in his garden shed, would you simply pray that God would use that family for his purposes? Now maybe you're not perfect either; maybe you row with your wife; maybe you're driving your teenage kids up the wall with your ranting about their behaviour; maybe you give your colleagues at work a rough time; maybe you don't always remember to declare everything to the IRS. But does that disqualify you from intervening? Surely God could use you to bring justice to the oppressed and protect the innocent, and then sort you out at a later date? It would be better, of course, if in taking action against an unrighteous and dangerous neighbour you recognized the obligation to act righteously yourself.
