NSB(i)
10 In this is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation (atonement) (sacrificial payment) for our sins.
11 Beloved, if God so loved us, we also ought to love one another.
12 No one has seen God at any time! If we love one another, God lives with us, and his love is perfected (accomplished) (matured) through us.
13 We know that we live with him and he with us, because he has given us of his Spirit.
14 We see and testify that the Father sent the Son to be the Savior of the world.
