The end of my pressing so much the duty of holiness upon you, under the notions of abiding in me, abiding in my love in my words, bringing forth much fruit, &c. is, that I might have a continual cause to rejoice in you. Joy is nothing else but the satisfaction of the reasonable soul in its union with an object which it loved and desired. Christ, willing and desiring the perfection of his disciples, according to the rational workings of human nature, is properly said to rejoice in the satisfaction of his will; in which sense joy and rejoicing are often in Scripture attributed to God. Nor doth Christ press them to this, that he might rejoice in them, but also that their joy might be full; that joy and peace which attends and follows believing, Romans 15:13; called the peace of God, Colossians 3:15; a peace which passeth all understanding, Philippians 4:7. No man maketh Christ to rejoice over him, but he thereby also procures unspeakable joy and peace to himself; as no man grieves his Spirit, but also purchases grief and sadness to himself in the latter end.
