One reason that determining the authorship of these [Johannine] letters is such a sticky question is that the writer’s visceral urge is to witness to God, into whose truth and love he has ventured far, not to present a profile of his personal identity and petty human expectations. His own personality is obscured by the divine person to whom he has so thoroughly subordinated his thoughts, actions, and affection. He writes like someone well might whom perhaps sixty years earlier Jesus taught to pray, “Your will be done,” and in composing these letters as a very old man has become an instrument of answer to his own daily petition.

–Robert W. Yarbrough, 1-3 John.
