1 John 4:12-15
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.
4:14 And we have seen and testify that the Father has sent the Son to be the Savior of the world.
4:15 If anyone confesses that Jesus is the Son of God, God resides in him and he in God.
