"Let there be no mistake. These chapters are not concerned to present the disciple as a genius. The genius is not in failing man but in the power of God. It is that process which transforms the disciple into the friend, the witness, the servant of the Master. It is that system of living, which changes failure into fulfillment and finally into victory.

True discipleship involves the whole man and its influence should be conspicuous in every department of daily living. The objective is conformity of the disciple's mind and will to the image of Christ, so that finally, when the Lord comes again, the whole man, body, soul, and spirit may be changed and fashioned like unto him, immortal and incorruptible. But now, while he tarries, the purpose is to create and develop faithful and consecrated souls, upon whom he can depend, through whom he may witness and by whom his cause is advanced in this world. The making of such through all the varied ways of life is the genius of discipleship." ~Genius of Discipleship, preface
