19 We have the power of loving, because he first had love for us.
20 If a man says, I have love for God, and has hate for his brother, his words are false: for how is the man who has no love for his brother whom he has seen, able to have love for God whom he has not seen?
21 And this is the word which we have from him, that he who has love for God is to have the same love for his brother.

Commentary on 1 John 4 Matthew Henry Commentary
Chapter 4
In this chapter the apostle exhorts to try spirits (v. 1), gives a note to try by (v. 2, 3), shows who are of the world and who of God (v. 4-6), urges Christian love by divers considerations (v. 7-16), describes our love to God, and the effect of it (v. 17-21).
1Jo 4:1-3
The apostle, having said that God's dwelling in and with us may be known by the Spirit that he hath given us, intimates that that Spirit may be discerned and distinguished from other spirits that appear in the world; and so here,

1Jo 4:7-13
As the Spirit of truth is known by doctrine (thus spirits are to be tried), it is known by love likewise; and so here follows a strong fervent exhortation to holy Christian love: Beloved, let us love one another, v. 7. The apostle would unite them in his love, that he might unite them in love to each other: "Beloved, I beseech you, by the love I bear to you, that you put on unfeigned mutual love.' This exhortation is pressed and urged with variety of argument: as,
1Jo 4:14-16
Since faith in Christ works love to God, and love to God must kindle love to the brethren, the apostle here confirms the prime article of the Christian faith as the foundation of such love. Here,
1Jo 4:17-21
The apostle, having thus excited and enforced sacred love from the great pattern and motive of it, the love that is and dwells in God himself, proceeds to recommend it further by other considerations; and he recommends it in both the branches of it, both as love to God, and love to our brother or Christian neighbour.
