Verse 4.— He that saith, I know him, and keepeth not. Any one who asserts that he knows God, and does not keep his commandments, John says of such an one two things: 1. He is a liar. 2. The truth is not in him. These are fearful declarations. They come, however, from inspira tion. "He that heareth you, heareth me, and he that heareth me, heareth him that sent me." The plainness of speech here is specially significant. Evidently, God intended that his servant, John, should leave no ground for mistake or blunder.
