“By this everyone will know that you are my disciples, if you love one another.”John 13:35
Key to understanding this verse is to see the themes of John 13:31-17:26 (The Farewell Discourse):
Receiving God inevitably involves joining the disciples in receiving the entire community of God. One ends up loving whoever God dwells in, whoever he works in, whoever he speaks through, and whoever he sends.
Rejecting God inevitably involves joining the world in rejecting the entire community of God. One ends up hating whoever God dwells in, whoever he works in, whoever he speaks through, and whoever he sends.
The Father sends his Son. The Son gives the Spirit who proceeds from the Father. And the disciples are indwelled by the Father and the Son through the Spirit. The disciples are even in the Father and the Son. And the disciples, in concert with the Father, Son, and Spirit, speak words given to them, by the authority of the one who sent them, and seek to glorify the one who sent them.
Those who hate the Son or his disciples are judged: they are eventually exposed as hating, in concert with the world, the entire mutually-indwelling community of the Father, and the Son, and the Spirit, and the disciples.
Those who love the Son are given a glory, a mission, a home, an indwelling, an enduring peace, a Comforter, a new commandment, and words to speak, in concert with the entire mutually-indwelling community of the Father, and the Son, and the Spirit, and other disciples.
Therefore to be of the disciples, to abide in the true vine, to abide in the words of the Son, to have the Spirit dwelling within you, to have the Father “pruning” you, and making his home in you, and to love other disciples who are undergoing the same renovation and enjoying the mutually-indwelling community, is to provide a witness to the world that forces others to wholly accept or wholly reject both the Father and the Son.
To receive the Son as the one sent by the Father, and as the one dwelling in his sent people.
Or to reject and, eventually, to discover oneself as hating and opposing all of them.
The disciples who love one another are chosen out of the world and hated by the world.
But the disciples love the one who lives in other disciples.
They make their home with those who have their home prepared by Christ.
They make their home with those the Father has made his home with.
They dwell with those whom the Father and the Son dwell in.
They love those whom the Father loves, and the Father loves those who love his Son.
“By this everyone will know that you are my disciples, if you love one another.” (John 13:35)
Please read John 13:31-17:26 and test these things.
The indwelling has a direction: it begins with the Father and the Son who was loved by the Father before the foundation of the world. We receive, they give. We give only what we have received. We are only given glory or a mission or an indwelling or a message so that we may glorify the one who sent us.
