The one who says he is in the light but hates his brother is in the darkness until now. The one who loves his brother remains in the light, and there is no cause for stumbling in him.

1 John 3:14-18

We know that we have passed from death to life because we love our brothers. The one who does not love remains in death. Everyone who hates his brother is a murderer, and you know that no murderer has eternal life residing in him. This is how we have come to know love: He laid down His life for us. We should also lay down our lives for our brothers. read more.
If anyone has this world's goods and sees his brother in need but shuts off his compassion from him-how can God's love reside in him? Little children, we must not love in word or speech, but in deed and truth;

Knowledge » Who does not know God

1 John 4:8

1 John 3:1-6

Look at how great a love the Father has given us, that we should be called God's children. And we are! The reason the world does not know us is that it didn't know Him. Dear friends, we are God's children now, and what we will be has not yet been revealed. We know that when He appears, we will be like Him, because we will see Him as He is. And everyone who has this hope in Him purifies himself just as He is pure. read more.
Everyone who commits sin also breaks the law; sin is the breaking of law. You know that He was revealed so that He might take away sins, and there is no sin in Him. Everyone who remains in Him does not sin; everyone who sins has not seen Him or known Him.

Love » The source of love

1 John 4:7-21

Dear friends, let us love one another, because love is from God, and everyone who loves has been born of God and knows God. The one who does not love does not know God, because God is love. God's love was revealed among us in this way: God sent His One and Only Son into the world so that we might live through Him. read more.
Love consists in this: not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. Dear friends, if God loved us in this way, we also must love one another. No one has ever seen God. If we love one another, God remains in us and His love is perfected in us. This is how we know that we remain in Him and He in us: He has given to us from His Spirit. And we have seen and we testify that the Father has sent the Son as Savior of the world. Whoever confesses that Jesus is the Son of God-God remains in him and he in God. And we have come to know and to believe the love that God has for us. God is love, and the one who remains in love remains in God, and God remains in him. In this, love is perfected with us so that we may have confidence in the day of judgment; for we are as He is in this world. There is no fear in love; instead, perfect love drives out fear, because fear involves punishment. So the one who fears has not reached perfection in love. We love because He first loved us. If anyone says, "I love God," yet hates his brother, he is a liar. For the person who does not love his brother whom he has seen cannot love God whom he has not seen. And we have this command from Him: the one who loves God must also love his brother.
