he who says he remains in him ought himself also to walk just like he walked.

 Beloved is John's favourite address to his people (compare 1 John 3:2; 1 John 3:21; 1 John 4:1; 1 John 4:7; 3 John 1:1-2; 3 John 1:5; 3 John 1:11). The whole accent of his writing is love. As Westcott puts it: "St. John, while enforcing the commandment of love, gives expression to it." There is something very lovely here. So much of this letter is a warning; and parts of it are rebuke. When we are warning people or rebuking them, it is so easy to become coldly critical; it is so easy to scold; it is even possible to take a cruel pleasure in seeing people wince under our verbal lash. But, even when he has to say hard things, the accent of John's voice is love. He had learned the lesson which every parent, every preacher, every teacher, every leader must learn; he had learned to speak the truth in love.
