John 15:9

As the Father hath loved me
As his own Son, and as Mediator, from everlasting; and in time, in his state of humiliation, throughout the course of his obedience, and under all his sufferings; which he testified more than once by a voice from heaven; which he showed by concealing nothing from him as Mediator, by giving all things into his hands, by showing him all that he himself did, by appointing him the Saviour of the body, and making him the head of the church, by exalting him at his right hand, and ordaining him to be judge of quick and dead.

So have I loved you:
Christ loves his as his spouse and bride, as his dear children, as members of his body, as branches in him the vine, as believers in him, and followers of him; which he has shown by espousing both their persons and cause, by assuming their nature, by suffering and dying in their room and stead, and making all suitable provision for them, both for time and eternity. And there is a likeness between the Father's love to him, and his love to his disciples and followers: as his Father loved him from everlasting, so did he love them; as his Father loved him with a love of complacency and delight, so did he, and so does he love them; and as his Father loved him with a special and peculiar affection, with an unchangeable, invariable, constant love, which will last for ever, in like manner does Christ love his people; and with this he enforces the following exhortation.

Continue ye in my love:
meaning either in his love to them, which, as he always continues in it without any variableness or shadow of turning, so he would have them continue in believing their interest in it, prizing and valuing it, in imitating and remembering it; or else in their love to him, to his person, to his people, to his Gospel, to his ordinances, ways, and worship, which he knew was liable to wax cold, though it could not be lost.
