God is Love

Commenting on 1 Jn. 4:16, Jonathan Edwards says this of the Spirit:

The Apostle tells us that 'God is love; and he that dwelleth in love dwelleth in God, and God in him.' Which confirms not only that the divine nature subsists in love, but also that this love is the Spirit: for it is the Spirit of God by which God dwells in his saints, as the Apostle had observed in the thirteenth verse, and as we are abundantly taught in the New Testament.
