By this the love (agapē | ἀγάπη | nom sg fem) of God is revealed to us: that God has sent his one and only Son into the world so that we might live through him.

The person who does not love does not know God, because God is love (agapē | ἀγάπη | nom sg fem).

Dear friends, let us love one another, because love (agapē | ἀγάπη | nom sg fem) is from God, and everyone who loves has been born of God and knows God.

But whoever has this world’s resources and sees his fellow Christian in need yet closes his heart against him, how does the love (agapē | ἀγάπη | nom sg fem) of God abide in him?

By this we have come to know love: (agapēn | ἀγάπην | acc sg fem) that he laid down his life on our behalf. And we are obligated to lay down our lives for the brothers.

See what great love (agapēn | ἀγάπην | acc sg fem) the Father has given to us, that we should be called children of God — and so we are! The reason the world does not know us is that it did not know him.

Do not love the world or the things in the world. If anyone loves the world, the love (agapē | ἀγάπη | nom sg fem) of the Father is not in him.

But whoever keeps his word, truly in that person is the love (agapē | ἀγάπη | nom sg fem) of God brought to fulfillment. This is how we can be sure that we are in him:

by godliness brotherly affection, and by brotherly affection love (agapēn | ἀγάπην | acc sg fem).

Greet one another with the kiss of love (agapēs | ἀγάπης | gen sg fem). Peace be with all of you who are in Christ.
