What happened to the human race from the Tower of Babel until Abraham?
The human race declined from the Tower of Babel until Abraham. God gave them up to a lower lifestyle than they began with, and the decline continued until God had to call out one man, Abraham, to do something different.
Les explains that from the Tower of Babel, the human race experienced a steady decline, going "down, down, down" until God finally had to say, "I'm going to call out one man, and I'm going to do something different," which was the call of Abraham. This pattern of decline also happened to Israel, which started with the knowledge of God but degenerated until there was no remedy. Les compares it to empires and nations, like Europe after the Reformation, which began with high spirituality but degenerated. He also uses Pharaoh as an example: each rejected plague was worse than the previous, and Egypt ended up a shambles due to arrogance. So the human race from Babel to Abraham followed this same downward spiral.
