what is God warning about human nature and future generations?

Les teaches that God is warning that human nature itself will carry its traits forward generation after generation. He illustrates this with a child pulling the wings off a butterfly: the child vents feelings on something beneath him because he cannot compete against those above him. That, Les says, is exactly how the whole human makeup operates until the power of a sovereign God comes into that life. Society is in its present shape because people have pushed God out of their thinking, schools, and homes, and then decry what is happening. God's warning is that these traits will take off down the line generation after generation, as seen in alcoholism repeating generation after generation. Scripture said this 1,500 years before Christ, so it is not merely a new discovery by modern medical people.
