John had an important and urgent message to share with the elect lady and her children. As such, he wrote this short epistle to warn of the deceivers who would lead them to forfeit their reward.
However, in the final few lines of his letter, he wrote of a preference to communicate with them “face to face.” Letters could not adequately express either his love for them, or the urgency of his warnings.
Each of us know the truth of Paul’s words. We read fondly the letters of love and devotion sent my family and friends. However, our “joy” is full when we see them in the flesh.
Too, the electronic correspondence of our generation is a pale facsimile of personal communication. “LOL” is an inadequate imitation of the laughter and love we share when we are together. Speaking “face to face” is the better way.
