10 Love lies in this, not in our love for him but in his love for us — in the sending of his Son to be the propitiation for our sins.
11 Beloved, if God had such love for us, we ought to love one another.
12 God no one has ever seen; but if we love one another, then God remains within us, and love for him is complete in us.
13 This is how we may be sure we remain in him and he in us, because he has given us a share in his own Spirit;
14 and we have seen, we can testify, that the Father has sent the Son as the Saviour of the world.
15 Whoever confesses that 'Jesus is the Son of God,' in him God remains, and he remains in God;
16 well, we do know, we have believed, the love God has for us. God is love, and he who remains in love remains in God, and God remains in him.
17 Love is complete with us when we have absolute confidence about the day of judgment, since in this world we are living as He lives.
18 Love has no dread in it; no, love in its fulness drives all dread away, for dread has to do with punishment — anyone who has dread, has not reached the fulness of love.
19 We love, because He loved us first.
