1 John 4:15-21
15If anyone acknowledges that Jesus is the Son of God, God lives in them and they in God.
16And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in them.
17This is how love is made complete among us so that we will have confidence on the day of judgment: In this world we are like Jesus.
18There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love.
19We love because he first loved us.
20Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen.
21And he has given us this command: Anyone who loves God must also love their brother and sister.
