Verses 16, 17. - The nature of love as shown by Christ, and its obligation on Christians. Love has been declared the criterion for distinguishing the children of God from the children of the devil. It remains to show what love is; and this is best seen in a concrete example. "The Eternal Word, incarnate and dying for the truth, inspires St. John to guard it with apostolic chivalry; but also this revelation of the heart of God melts him into tenderness towards the race which Jesus has loved so well. To St. John a lack of love for men seems sheer dishonour to the love of Christ" (Liddon). Verse 16. - In this (verse 10; 1 John 2:3)we have come to know (have acquired and possess the knowledge of) love (what love is), in that he laid down his life for us. This is better than "We have come to know love as consisting in this, that he laid down his life for us," which would have been ἐν τούτῳ οϋσαν. Cain is the type of hate; Christ, of love. Cain took his brother's life to benefit himself; Christ laid down his own life to benefit his enemies (see on John 10:12). This realized ideal of love we must imitate; ready to sacrifice ourselves, and even our lives, for the good of others. The effacement of another's rights and perhaps existence for one's own sake is the essence of hatred; the effacement of one's self for another's sake is the essence of love. Christ died for those who hated him; and the Christian must confront the hatred of the world with a love that is ready even to die for the haters. This shows that the "brethren" here and in verse 14, though used primarily of Christians, does not exclude unbelievers; otherwise the parallel with Christ would be spoiled (see on verse 10).
3:16-21 Here is the condescension, the miracle, the mystery of Divine love, that God would redeem the church with his own blood. Surely we should love those whom God has loved, and so loved. The Holy Spirit, grieved at selfishness, will leave the selfish heart without comfort, and full of darkness and terror. By what can it be known that a man has a true sense of the love of Christ for perishing sinners, or that the love of God has been planted in his heart by the Holy Spirit, if the love of the world and its good overcomes the feelings of compassion to a perishing brother? Every instance of this selfishness must weaken the evidences of a man's conversion; when habitual and allowed, it must decide against him. If conscience condemn us in known sin, or the neglect of known duty, God does so too. Let conscience therefore be well-informed, be heard, and diligently attended to.
Hereby perceive we the love of God,.... The phrase "of God" is not in the Oriental versions, nor in the Greek copies, but is in the Complutensian edition, and in the Vulgate Latin version, and is favoured by the Syriac version, which reads, "by this we know his love to us"; and so the Ethiopic version, "by this we know his love". That is, the love of the Lord Jesus Christ, who is truly and properly God, the great God, the mighty God, the true God, and God over all, blessed for ever. His love is manifested to his people, and perceived by them in various instances; but in nothing is it more clearly seen than in the following one:
because he laid down his life for us: of the life of Christ, and his laying it down in the room of his people; see Gill on , which shows his love, his free grace and favour; for this arose not from any merit or worth in the persons he died for; not from their love, loveliness, or duty, but from his rich mercy, and the great love wherewith he loved them; and which, though it cannot be equalled, should be imitated:
and we ought to lay down our lives for the brethren: not in such sense, or for such ends and purposes, as Christ laid down his life for us; for no man, as by giving his money, so by laying down his life, can redeem his brother, or give to God a ransom for him: but the meaning is, that saints ought to risk their lives, and expose themselves to dangers, for the sake of their brethren, when they are called to it, and the case requires it: as Priscilla and Aquila laid down their necks, or ventured their lives for the Apostle Paul, Romans 16:3; and they should also, when called unto it, freely lay down their lives in the cause of Christ, and for the sake of his Gospel, for the gaining of souls to Christ, and for the confirming of the faith of the brethren in him, as the apostles of Christ, and the martyrs of Jesus, have done; this is an argument for brotherly love, in the highest instance of it, taken from the example of our Lord Jesus Christ, than which nothing is more forcible, or can lay a greater obligation on the saints.
