I John 4:7

Resumption of the main theme (Jo1 2:29). Love, the sum of righteousness, is the test of our being born of God. Love flows from a sense of God's love to us: compare Jo1 4:9 with Jo1 3:16, which Jo1 4:9 resumes; and Jo1 4:13 with Jo1 3:24, which similarly Jo1 4:13 resumes. At the same time, Jo1 4:7-21 is connected with the immediately preceding context, Jo1 4:2 setting forth Christ's incarnation, the great proof of God's love (Jo1 4:10). Beloved--an address appropriate to his subject, "love." love--All love is from God as its fountain: especially that embodiment of love, God manifest in the flesh. The Father also is love (Jo1 4:8). The Holy Ghost sheds love as its first fruit abroad in the heart. knoweth God--spiritually, experimentally, and habitually.

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, Jo1 4:7.

The Spirit of God is the Spirit of love. The new nature in the children of God is the offspring of his love: and the temper and complexion of it is love. The fruit of the Spirit is love, Gal 5:22. Love comes down from heaven. II. Love argues a true and just apprehension of the divine nature: He that loveth knoweth God, Jo1 4:7. He that loveth not knoweth not God, Jo1 4:8. What attribute of the divine Majesty so clearly shines in all the world as his communicative goodness, which is love. The wisdom, the greatness, the harmony, and usefulness of the vast creation, which so fully demonstrate his being, do at the same time show and prove his love; and natural reason, inferring and collecting the nature and excellence of the most absolute perfect being, must collect and find that he is most highly good: and he that loveth not (is not quickened by the knowledge he hath of God to the affection and practice of love) knoweth not God; it is a convictive evidence that the sound and due knowledge of God dwells not in such a soul; his love must needs shine among…
