14 And we have seen and testifyw that the Father has sent his Son to be the Savior of the world.x 15 If anyone acknowledges that Jesus is the Son of God,y God lives in them and they in God.z 16 And so we know and rely on the love God has for us.

God is love.a Whoever lives in love lives in God, and God in them.b 17 This is how love is made completec among us so that we will have confidenced on the day of judgment:e In this world we are like Jesus. 18 There is no fear in love. But perfect love drives out fear,f because fear has to do with punishment. The one who fears is not made perfect in love.

19 We love because he first loved us.g 20 Whoever claims to love God yet hates a brother or sisterh is a liar.i For whoever does not love their brother and sister, whom they have seen,j cannot love God, whom they have not seen.k 21 And he has given us this command:l Anyone who loves God must also love their brother and sister.m

Faith in the Incarnate Son of God

5 Everyone who believesn that Jesus is the Christo is born of God,p and everyone who loves the father loves his child as well.q 2 This is how we knowr that we love the children of God:s by loving God and carrying out his commands. 3 In fact, this is love for God: to keep his commands.t And his commands are not burdensome,u 4 for everyone born of Godv overcomesw the world. This is the victory that has overcome the world, even our faith. 5 Who is it that overcomes the world? Only the one who believes that Jesus is the Son of God.x
