Why is it hard to understand the church age and why God deals with us the way He does?

Les explains that after finishing 2 Corinthians, he set aside Galatians for at least one program because of many requests and comments about the timeline. He wanted to review once again the timeline, how everything unfolds, how it all fits, and how everything rests on that which is gone before. Consequently, he says, it is hard to understand the church age and why God is dealing with us the way He is unless we see where it all began. In his Oklahoma classes, people said that if he had ever done anything to open up the Bible, it was using the timeline. This review shows that the present church age cannot be understood apart from the foundation of what came before.
