John 15:9

Καθὼς ἠγάπησε … ἐμῇ. Love is the true bond which gives unity to the moral world, and inspires discipleship. All that Christ experiences is the result of the Father's love: all that the disciples are called to be and to do is the outcome of Christ's love. This love of Christ was to be retained as their possession by their conforming themselves to it: μείνατε ἐν τῇ ἀγάπῃ τῇ ἐμῇ, “abide in my love,” no longer “abide in me,” but specifically “in my love”. Abide in it, for there is a possibility of your falling away from its enjoyment and possession.
