7 Dear friends, let us love one another, because love is from God, and everyone who loves has been fathered by God and knows God. 8 The person who does not love does not know God, because God is love. 9 By this the love of God is revealed in us: that God has sent his one and only Son into the world so that we may live through him. 10 In this is love: not that we have loved God, but that he loved us and sent his Son to be the atoning sacrifice for our sins. 11 Dear friends, if God so loved us, then we also ought to love one another. 12 No one has seen God at any time. If we love one another, God resides in us, and his love is perfected in us. 13 By this we know that we reside in God and he in us: in that he has given us of his Spirit. 14 And we have seen and testify that the Father has sent the Son to be the Savior of the world.
