What are the three main points of the sermon Pastor Maxwell was preparing in the first chapter

From the text:

He had emphasized in the first part of the sermon the Atonement as a personal sacrifice, calling attention to the fact of Jesus' suffering in various ways, in His life as well as in His death. He had then gone on to emphasize the Atonement from the side of example, giving illustrations from the life and teachings of Jesus to show how faith in the Christ helped to save men because of the pattern or character He displayed for their imitation. He was now on the third and last point, the necessity of following Jesus in His sacrifice and example.
