1-е Иоанна 2:3

hereby--Greek, "in this." "It is herein," and herein only, that we know (present tense) that we have knowledge of (perfect tense, once-for-all obtained and continuing knowledge of) Him" (Jo1 2:4, Jo1 2:13-14). Tokens whereby to discern grace are frequently given in this Epistle. The Gnostics, by the Spirit's prescient forewarning, are refuted, who boasted of knowledge, but set aside obedience. "Know Him," namely, as "the righteous" (Jo1 2:1, Jo1 2:29); our "Advocate and Intercessor." keep--John's favorite word, instead of "do," literally, "watch," "guard," and "keep safe" as a precious thing; observing so as to keep. So Christ Himself. Not faultless conformity, but hearty acceptance of, and willing subjection to, God's whole revealed will, is meant. commandments--injunctions of faith, love, and obedience. John never uses "the law" to express the rule of Christian obedience: he uses it as the Mosaic law.

These verses may seem to relate to the seventh verse of the former chapter, between which and these verses there occurred an incidental discourse concerning the believer's duty and relief in case of sin, occasioned by the mention of one of the believer's privileges - his being cleansed from sin by the Mediator's blood. In that verse the apostle asserts the beneficial consequence of walking in the light: "We have then fellowship with one another, such divine fellowship and communion as are the prerogative of the church of Christ." Here now succeeds the trial or test of our light and of our love. I. The trial of our light: And hereby we do know that we know him, if we keep his commandments, Jo1 2:3. Divine light and knowledge are the beauty and improvement of the mind; it becomes the disciples of the Mediator to be persons of wisdom and understanding. Young Christians are apt to magnify their new light and applaud their own knowledge, especially if they have been suddenly or in a short time communicated; and old ones are apt to suspect the sufficiency and fulness of their knowledge; they lament that they know God, and Christ, and the rich contents of his gospel, no more: but here is the evidence of the soundness of our knowledge, if it constrain us to keep God's commandments. Each perfection of his nature enforces his authority; the wisdom of his counsels, the riches of his grace, the grandeur of his works, recommend his law and government. A careful conscientious obedience to his commands shows that the apprehension and knowledge of these things are graciously impressed upon the soul; and therefore it must follow in the reverse that he that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him, Jo1 2:4. Professors of the truth are of…

2:3-6 Obedience is one clear indication that we know Christ and belong to him. If we do not obey Christ, it is obvious that we do not belong to him or love him. • As we obey Christ and his commandments, our love for God and our knowledge of him will grow toward completeness and maturity. We will live . . . as Jesus did, in union with God and showing love for others.
