An important remind from this reading is that we are responsible for our own actions.  Amaziah could have put to death the children of those who led Judah in the wrong direction, but he didn't because the Law said that, "Fathers shall not die because of their children, nor children die because of their fathers, but each one shall die for his own sin" (2 Chronicles 25:4).  The point is that, regardless of your upbringing and how good or bad your parents were or are, there comes a point in time where you are accountable to God for your actions.  You can't blame your family anymore, and you can't claim "foul" for the way that you were raised.  Parent's, likewise, aren't responsible for their children after a certain time.  We each have wills of our own, and we answer to God for how we live.  The question is whether or not you're living in a way that's pleasing to the Lord.  One day you will answer to Him.  Take responsibility and quit blaming other people.
