Dear friends, let us love one another, because love is from God, and everyone who loves has been fathered by God and knows God.
The one who does not love does not know God, because God is love.
By this the love of God is revealed in us: that God sent his one and only Son into the world in order that we may live through him.
In this is love: not that we have 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 ought to love one another.
No one has seen God at any time. If we love one another, God resides in us and his love is perfected in us.
By this we know that we reside in him and he in us: that he has given us of his Spirit.
And we have seen and testify that the Father has sent the Son [to be the] Savior of the world.
Whoever confesses that Jesus is the Son of God, God resides in him and he in God.
And we have come to know and have believed the love that God has in us. God is love, and the one who resides in love resides in God, and God resides in him.
