John 15:1

Here Christ discourses concerning the fruit, the fruits of the Spirit, which his disciples were to bring forth, under the similitude of a vine. Observe here, I. The doctrine of this similitude; what notion we ought to have of it. 1. That Jesus Christ is the vine, the true vine. It is an instance of the humility of Christ that he is pleased to speak of himself under low and humble comparisons. He that is the Sun of righteousness, and the bright and morning Star, compares himself to a vine. The church, which is Christ mystical, is a vine (Psa 80:8), so is Christ, who is the church seminal. Christ and his church are thus set forth. (1.) He is the vine, planted in the vineyard, and not a spontaneous product; planted in the earth, for his is the Word made flesh. The vine has an unsightly unpromising outside; and Christ had no form nor comeliness, Isa 53:2. The vine is a spreading plant, and Christ will be known as salvation to the ends of the earth. The fruit of the vine honours God and cheers man (Jdg 9:13), so does the fruit of Christ's mediation; it is better than gold, Pro 8:19. (2.) He is the true vine, as truth is opposed to pretence and counterfeit; he is really a fruitful plant, a plant of renown. He is not like that wild vine which deceived those who gathered of it (Kg2 4:39), but a true vine.
