And we have known and believed the love that God has for us. God is love; and he that dwells in love dwells in God, and God in him.
Read Chapter 4
Augustine of Hippo
AD 430
And again, by what have you come to know this? Love is God. He has already said it above, behold he says it again. Love could not be more exceedingly commended to you than that it should be called God . Haply you were ready to despise a gift of God. And do you despise God? Love is God: and he that dwells in love dwells in God, and God dwells in him. Each mutually inhabites the other; He that holds, and he that is holden. You dwell in God, but that you may be holden: God inhabites you, but that He may hold you, lest you fall. Lest haply you imagine that you become an house of God in such sort as your house supports your flesh: if the house in which you are withdraw itself from under you, you fall, but if you withdraw yourself, God falls not. When you forsake Him, He is none the less; when you have returned unto Him, He is none the greater. You are healed, on Him you will bestow nothing; you are made clean, you are new-made, you are set right: He is a medicine to the unhealthy, is a rule...
You remember, beloved, that of the epistles of John the apostle the last past remains to be handled by us and expounded to you, as the Lord vouchsafes. Of this debt then we are mindful: and you ought to be mindful of your claim. For indeed this same charity, which in this epistle is chiefly and almost alone commended, at once makes us most faithful in paying our debts, and you most sweet in exacting your rights. I have said, most sweet in exacting, because where charity is not, he that exacts is bitter: but where charity is, both he that exacts is sweet, and he of whom it is exacted, although he undertakes some labor, yet charity makes the very labor to be almost no labor, and light. Do we not see how, even in dumb and irrational animals, where the love is not spiritual but carnal and natural, with great affection the mother yields herself to her young ones when they will have the milk which is their right: and however impetuously the suckling rushes at the teats, yet that is better fo...
And if "God be love "piety also is love: "there is no fear in love; but perfect love casteth out fear.".
It is not, then, without reason that we commanded boys to kiss their relations, holding them by the ears; indicating this, that the feeling of love is engendered by hearing. And "God "who is known to those who love, "is love"
And we know and have believed the love which God hath in us. In these words S. John confirms and inculcates what he has said in the two preceding verses. His meaning Isaiah , "We have seen and do testify of Christ incarnate, who is the Love of God, because we know Him by experience and conversation to be really such. And we have believed in Him by faith. Therefore we have believed the love which God hath in us, i.e, towards us, because we have believed that God in his infinite love towards us hath given to us Christ the Saviour. The Vulg. has in us, but the Syriac translates towards us. (So also the Eng. Version.)
Observe: S. John moves in a circle. From God he leaps to Christ, from Christ to charity, from charity to love of our neighbour, from charity and love he returns to God, thence to Christ, and so on. For all these things have reference to this one point, that we should love one another. And this is his argument, God in His infinite charity hath loved us, i.e. all men, by givin...
The word of the blessed Apostle John is: "God "saith he, "is love; and he that dwelleth in love dwelleth in God, and God dwelleth in him.".
Also in the Epistle of John: "God is love l and he that dwelleth in love dwelleth in God, and God in him."
