"Thus the test suggested by 1 John 2:3 is not of the saving knowledge of God or of Christ, but of the experiential knowledge of God and His Son. To get this wrong, as many commentators have, is to lay the groundwork for a complete misreading of the epistle! Such a misreading is indeed common in the commentaries today and may be traced back primarily to Robert Law’s study on this epistle." [Note: Hodges, The Epistles . . ., pp. 75-77.]
