¹³ This is how we know we remain in him and he remains in us, because he has given us a measure of his Spirit. ¹⁴ We have seen and testify that the Father has sent the Son to be the savior of the world. ¹⁵ If any of us confess that Jesus is God’s Son, God remains in us and we remain in God. ¹⁶ We have known and have believed the love that God has for us.

God is love, and those who remain in love remain in God and God remains in them. ¹⁷ This is how love has been perfected in us, so that we can have confidence on the Judgment Day, because we are exactly the same as God is in this world. ¹⁸ There is no fear in love, but perfect love drives out fear, because fear expects punishment. The person who is afraid has not been made perfect in love. ¹⁹ We love because God first loved us. ²⁰ Those who say, “I love God” and hate their brothers or sisters are liars. After all, those who don’t love their brothers or sisters whom they have seen can hardly love God whom they have not seen! ²¹ This commandment we have from him: Those who claim to love God ought to love their brother and sister also.
