Hereby we do know that we, truly and savingly, know him As he is the Advocate, the righteous One, the Propitiation; if we keep his commandments Particularly those of faith and love. He that saith, I know him, and keepeth not his commandments, is a liar “The Nicolaitans and Gnostics, notwithstanding they lived in an habitual course of the most criminal sensual indulgences, boasted that they were the objects of God's love, and sure of obtaining eternal life, merely because they possessed the knowledge of the true God, and of his mercy in forgiving men's sins. In this boasting the apostle declared them liars, either because they spake what they knew to be false, or at least what was in itself most false.” But whoso keepeth his word Sincerely endeavours to live in obedience to all his commands; in him verily is the love of God Reconciled to us through Christ; perfected Perfectly known, or shows itself to be sincere. See on 1 John 4:12. Hereby By our keeping his word; know we that we are in him Truly united to him by a lively faith, and have communion with him. So is the tree known by its fruits. To know him, to be in him, to abide in him, are nearly synonymous terms; only with a gradation: knowledge, communion, constancy. He that saith he abideth in him An expression which implies a durable state; a constant, lasting knowledge of and communion with him; ought himself Otherwise they are vain words; so to walk, even as he walked In the world. As he are words that frequently occur in this epistle. Believers, having their hearts full of him, easily supply his name.
