John 20:30

The life of Jesus has now been traced from His eternal pre-existence as the Logos, through His manifestation of Himself in action and suffering upon earth, to the beginning of His glorification. The Evangelist has thus accomplished the purpose that he had proposed to himself; and he now sums up the particulars of the picture that he has presented, and states the nature of the end that it is designed to serve. It has indeed been urged that the verses before us are the conclusion only of the history of Jesus after His resurrection, and not of the whole history given in the Gospel. It is enough to say that this supposition is refuted by the words ‘this book,' and by what we shall find to be the purport of the verses.
