When I was a young man working as a computer programmer in a subbasement office, I met a man who had been badly maimed by a grenade thrown in his tank in World War II.  He gave me a perspective of God and our dependence on God that is reflected in a very unusual Psalm - number 37.  This Psalm is very much in the Wisdom literature category.  It tells us just how God deals with those who do good and those who do evil - and therefore how we should live each day.
