Before · 1 John 4:11–12
11Beloved, if God loved us in this way, we also ought to love one another. 12No one has seen God at any time. If we love one another, God remains in us, and his love has been perfected in us.
13By this we know that we remain in him and he in us, because he has given us of his Spirit.
