1 John 4:9-14

9 By this was God's love revealed in us, that God has sent his one and only Son into the world that we might live through him.  10 In this is love, not that we loved God, but that he loved us, and sent his Son as the atoning sacrifice for our sins.  11 Beloved, if God loved us in this way, we also ought to love one another.  12 No one has seen God at any time. If we love one another, God remains in us, and his love has been perfected in us.  13 By this we know that we remain in him and he in us, because he has given us of his Spirit.  14 We have seen and testify that the Father has sent the Son as the Savior of the world.
