Beloved, let us love one another: for love is of God; and everyone that loves is born of God, and knows God.
All Commentaries on 1 John 4:7 Go To 1 John 4
Augustine of Hippo
AD 430
If we are born of God, beloved, 1 John 4:7 he goes on— see above from what: We are of God: he that knows God hears us; he that is not of God hears not us. Hereby know we the spirit of truth, and of error: aye, now, he makes us eagerly attentive: to be told that he who knows God, hears; but he who knows not, hears not; and that this is the discerning between the spirit of truth and the spirit of error: well then, let us see what he is about to advise; in what we must hear him— Beloved, let us love one another. 1 John 4:7 Why? Because a man advises? Because love is of God. Much has he commended love, in that he has said, Is of God: but he is going to say more; let us eagerly hear.
