That's what maturity and age are all about. But parents lay the foundation and give children something to build upon. Just because a child goes bad is no proof that a parent failed, but it is one question among many that deserves consideration. Today's parents need to know the power of involvement in their children's lives. It can't be turned over to TV sets, video games, computer terminals, nor to sports or even educational activities.
Parents are vital to the formation of hearts.
A coach might develop athletic skills. A teacher might develop academic prowess. Friends might help a child develop social skills. Parents are in the heart-forming business, and it is ultimately the heart that produces good or evil, godliness or ungodliness. I'm not saying this to place blame for the Colorado tragedy.
