He who says he is in the light, and hates his brother, is in darkness even until now. But he who loves his brother is abiding in the light, and in it there is no cause of stumbling.

1 John 3:14-18

We know that we have migrated, out of death into life, because we love our brothers. He who has no love is abiding in death. Every one who is hating his brother is a murderer, and you know that no murderer has eternal life abiding in him. By this we learn to know love, because he laid down his life for us; so we ought to lay down our lives for our brothers. read more.
But whoever has this world's goods, and beholds his brother in need, and shuts up his heart against him, how can the love of God continue to abide in him? My children, let us not love in word nor in talk, but in deed and in truth.

1 John 4:7-11

Knowledge » Who does not know God

1 John 4:8

1 John 3:1-6

Behold what manner of love the Father has given us in allowing us to be called "Children of God!" And that is what we are. For this reason the world does not recognize us, because it did not know him. We are God's children now, beloved; what we shall be has never yet been made manifest. But we know that when he is manifested we shall be like him; for we shall see him even as he is. And every one who is holding this hope in him is purifying himself, even as he is pure. read more.
Every one who commits sin commits also lawlessness. Sin is lawlessness. And you know that he was manifested to take away sins; and in him is no sin. Whoever continually abides in him does not habitually sin; whoever lives in sin has not seen him, nor come to know him.

Love » Those that do not love others

1 John 3:10

In this the children of God are manifest, and the children of the devil; for every one who does not work righteousness is not a child of God, nor is he who does not love his brother. Verse Concepts

1 John 4:8

Love » God being love

1 John 4:7-8

Beloved, let us love one another; for love is of God; and every one that loves us a child of God. He who does not love, does not know God; for God is love.

Love » The source of love

1 John 4:7-21

Beloved, let us love one another; for love is of God; and every one that loves us a child of God. He who does not love, does not know God; for God is love. In this was the love of God clearly shown toward us, by his sending his only Son into the world, so that we might live through him. read more.
In this is love, not that we loved God, but that he loved us, and sent his Son to be a propitiation for our sins. If God so loved us, beloved, we also ought to love one another. No man has ever gazed on God; but if we love one another, God ever abides in us, and his love is perfected in us. By this we come to know that we are abiding in him, and he in us, because he has given us of his Spirit; and we have beheld and do testify that the Father has sent the Son to be the Saviour of the world. If any man confesses that "Jesus is the Son of God." God is abiding in that man, and he in God. And we do know and have believed the love which God has for us. God is love; and he who is abiding in love is abiding in God, and God is abiding in him. In this is love made perfect with us, so that we may have cheerful confidence in the Day of Judgment, because we are living in this world as He lives. Fear does not exist in love; but love, when it is perfect, drives out fear. For fear has always torment, and he who has fear is not yet perfected in love. We love because He loved us first. If any one says, "I love God," and yet hates his brother, he is a liar; for he who does not love his brother whom he has seen, cannot possibly love God, whom he has not seen. And we have this command from God: HE WHO LOVES GOD IS TO LOVE HIS BROTHER ALSO.
