4:11 Dear friends, if God so loved us, then we also ought to love one another. 4:12 No one has seen God at any time. If we love one another, God resides in us, and his love is perfected in us. 4:13 By this we know that we reside in God and he in us: in that he has given us of his Spirit.
4:15 If anyone confesses that Jesus is the Son of God, God resides in him and he in God. 4:16 And we have come to know and to believe 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. 4:17 By this love is perfected with us, so that we may have confidence in the day of judgment, because just as Jesus is, so also are we in this world.
