Who's the main character?

If your life was cast as a movie, who would be the main character? In Genesis 4 there is a contrast between two lines or generations of people. The one line has great accomplishments. They build cities and contribute a lot to the arts, sciences, technology and advancement. But they turn away from God and live for themselves. The 2nd line of people is known for one thing: they worship the Lord. They live with God at the center. Two lines...one is known for the worship of God and the other for worship of self.
