Matthew Poole and continuators on John 15:8

8 Herein is my Father glorified, that ye bear much fruit q, so shall ye be my Disciples .

And tho men must be Christ's Disciples before they bring forth any fruit, yet their bringing forth much fruit is that which alone can evidence and make them appear to be the Disciples of Christ. And often in Scripture being signifieth appearing, as Iohn 8.31. Rom. 3.4.

Here are Two Arguments to press his Disciples abiding in him, that so they might bring forth much fruit. 1. Herein (saith our Saviour) is my Father glorified. The glorifying of God is the great end of our lives, 1 Cor. 10.31. God is glorified by men and womens bringing forth much fruit, Matth. 5.16. the fruit unto holinese, Rom. 6.22. fruit in the product of the Plant, from the natural moisture that is in it, nourished and augmented by the fatness of the Earth in which it stands, and by the warmth of the Sun drawn out to the producing of such effects, according to the nature of the Plant. According to the different nature of Plants they bring forth various fruits, Matth. 7.16, 17, 18. Hence we read of the fruit of sin unto death, and the fruit of righteousness unto life. The first is every man's natural fruit, until he be ingrafted into Christ: being ingrafted into him, the soul having a new Nature given to it, being regenerated and renewed by the Holy Ghost, it no longer bringeth forth fruit from its old Principle, and according to its old nature, but from its new Principle, and according to its new nature; as the cultivated Earth that is plowed and harrowed, doth not bring forth Weeds and ordinary Grass, according to its nature, but bringeth forth fruit according to the Seed that is cast into it, yet not without the influence of Heaven, both with respect to the dew of it, and the warmth which it hath from the Sun; so the soul being regenerated, the fallow ground of it being plowed up, and the seed of righteousness being sown in it, it no more brings forth the weeds of lusts and corruptions, or onely ordinary acts of humane nature, but it brings forth fruits according to its new nature, and the new seed of the Word now sown in it, and dwelling in it. And look, as it tendeth to the honour of the Husbandman, when the ground by him plowed and manured, brings forth much fruit; so it tendeth to the honour and glory of God, when t[illegible: 1 letter]e souls renewed, manured, and influenced by him, bring forth much of the fruit of righteousness and holiness.
