Kagawa's life has been a witness to the redemptive power of love and from his vast experience he has drawn for the chapters of this book. Men and women high and low, rich and poor, good and bad, bear out the effectiveness of the gospel message. It changes lives and ambitions. It sent Kagawa to the slums to live and to palaces to preach. There are no barriers of race, creed or color in Kagawa's life and the sale of his book is universal too.
