These lectures were originally printed in "Father's Course and our Life of Faith, 21 Lectures by Won Pil Kim." The forward to the book says:

The lectures in this book were given by Father's first disciple, Won Pil Kim, as part of a 21-day leadership course held in London in 1979. Mr. Kim gave the lectures in Japanese. The English translation has been edited as sparingly as possible. May this book serve as a source of life and inspiration for the years to come to brothers and sisters throughout the world who are following in the footsteps of our True Parents.
