4:14-21 The Father sent the Son, he willed his coming into this world. The apostle attests this. And whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God. This confession includes faith in the heart as the foundation; makes acknowledgment with the mouth to the glory of God and Christ, and profession in the life and conduct, against the flatteries and frowns of the world. There must be a day of universal judgment. Happy those who shall have holy boldness before the Judge at that day; knowing he is their Friend and Advocate! Happy those who have holy boldness in the prospect of that day, who look and wait for it, and for the Judge's appearance! True love to God assures believers of God's love to them. Love teaches us to suffer for him and with him; therefore we may trust that we shall also be glorified with him, 2Ti 2:12. We must distinguish between the fear of God and being afraid of him; the fear of God imports high regard and veneration for God. Obedience and good works, done from the principle of love, are not like the servile toil of one who unwillingly labours from dread of a master's anger. They are like that of a dutiful child, who does services to a beloved father, which benefit his brethren, and are done willingly. It is a sign that our love is far from perfect, when our doubts, fears, and apprehensions of God, are many. Let heaven and earth stand amazed at his love. He sent his word to invite sinners to partake of this great salvation. Let them take the comfort of the happy change wrought in them, while they give him the glory. The love of God in Christ, in the hearts of Christians from the Spirit of adoption, is the great proof of conversion. This must be tried by its effects on their temper, and their conduct to their brethren. If a man professes to love God, and yet indulges anger or revenge, or shows a selfish disposition, he gives his profession the lie. But if it is plain that our natural enmity is changed into affection and gratitude, let us bless the name of our God for this seal and earnest of eternal happiness. Then we differ from the false professors, who pretend to love God, whom they have not seen, yet hate their brethren, whom they have seen.

17, 18. (Compare 1Jo 3:19-21.)

our love—rather as the Greek, "LOVE (in the abstract, the principle of love [Alford]) is made perfect (in its relations) with us." Love dwelling in us advances to its consummation "with us" that is, as it is concerned with us: so Greek. Lu 1:58, "showed mercy upon (literally, 'with') her": 2Jo 2, the truth "shall be with us for ever."

boldness—"confidence": the same Greek as 1Jo 3:21, to which this passage is parallel. The opposite of "fear," 1Jo 4:18. Herein is our love perfected, namely, in God dwelling in us, and our dwelling in God (1Jo 4:16), involving as its result "that we can have confidence (or boldness) in the day of judgment" (so terrible to all other men, Ac 24:25; Ro 2:16).

because, &c.—The ground of our "confidence" is, "because even as He (Christ) is, we also are in this world" (and He will not, in that day, condemn those who are like Himself), that is, we are righteous as He is righteous, especially in respect to that which is the sum of righteousness, love (1Jo 3:14). Christ IS righteous, and love itself, in heaven: so are we, His members, who are still "in this world." Our oneness with Him even now in His exalted position above (Eph 2:6), so that all that belongs to Him of righteousness, &c., belongs to us also by perfect imputation and progressive impartation, is the ground of our love being perfected so that we can have confidence in the day of judgment. We are in, not of, this world.
