The power of wrong, Psalms 91-94 today

How many wild-eyed characters have we seen or read spurting forth, "Vengeance is mine saith the Lord." The crazed character has been pushed to the edge of her or his tolerance for what is wrong with the world. The Power of Wrong is about to overwhelm. So, justice is taken into the hand of a man or woman. And, mostly the actions taken are themselves wrong. Psalm 94 speaks of God of vengeance but not a God who picks off the wrong doers to defend the right doer. Vengeance as James L May comments is "a plea for the Lord to vindicate his reign by intervening in the human situation in a time when wrong is rampant. Vengeance is not from the anger of the Lord but from the One who is the ruler of all creation to bring about the balance of justice. It does not mean the wrong does are wiped out, that is the human solution. Vengeance is God reasserting what is right. How do we rather than destroy what is wrong bring out that which is the love of God for all?
