John Gill -- John 15:2-4, 6

John 15: 2
Every branch in me that beareth not fruit,.... There are two sorts of branches in Christ the vine; the one sort are such who have only an historical faith in him, believe but for a time, and are removed; they are such who only profess to believe in him, as Simon Magus did; are in him by profession only; they submit to outward ordinances, become church members, and so are reckoned to be in Christ, being in a church state, as the churches of Judea and Thessalonica, and others, are said, in general, to he in Christ; though it is not to be thought that every individual person in these churches were truly and savingly in him. These branches are unfruitful ones; what fruit they seemed to have, withers away, and proves not to be genuine fruit; what fruit they bring forth is to themselves, and not to the glory of God, being none of the fruits of his Spirit and grace: and such branches the husbandman

taketh away; removes them from that sort of being which they had in Christ. By some means or another he discovers them to the saints to be what they are; sometimes he suffers persecution to arise because of the word, and these men are quickly offended, and depart of their own accord; or they fall into erroneous principles, and set up for themselves, and separate from the churches of Christ; or they become guilty of scandalous enormities, and so are removed from their fellowship by excommunication; or if neither of these should be the case, but these tares should grow together with the wheat till the harvest, the angels will be sent forth, who will gather out of the kingdom of God all that offend and do iniquity, and cast them into a furnace of fire, as branches withered, and fit to be burnt.
And every branch that beareth fruit, he purgeth it, that it may bring forth more fruit. These are the other sort of branches, who are truly and savingly in Christ; such as are rooted in him; to whom he is the green fir tree, from whom all their fruit is found; who are filled by him with all the fruits of his Spirit, grace, and righteousness. These are purged or pruned, chiefly by afflictions and temptations, which are as needful for their growth and fruitfulness, as the pruning and cutting of the vines are for theirs; and though these are sometimes sharp, and never joyous, but grievous, yet they are attended with the peaceable fruits of righteousness, and so the end of bringing forth more fruit is answered; for it is not enough that a believer exercise grace, and perform good works for the present, but these must remain; or he must be constant herein, and still bring forth fruit, and add one virtue to another, that it may appear he is not barren and unfruitful in the knowledge of Christ, in whom he is implanted. These different acts of the vinedresser "taking away" some branches, and "purging" others, are expressed by the Misnic doctors {p} by hlwoyp, and hdwryz. The former, the commentators {q} say, signifies to cut off the branches that are withered and perished, and are good for nothing; and the latter signifies the pruning of the vine when it has a superfluity of branches, or these extend themselves too far; when some are left, and others taken off.

Verse 3
Now ye are clean through the word which I have spoken unto you.. These words being inserted in the discourse concerning the vine and branches, and the pruning and purging them to make them fruitful, are thought, by the learned Dr. Lightfoot, to be an allusion to the law in Le 19:23; by which the fruit of trees, for the first three years, were accounted uncircumcised or unclean, and in the fourth year fit for use; concerning which the Talmudists have a whole tract, called hlre, "Orla"; the apostles having enjoyed the ministry of Christ, and been his disciples about such a time. Though the "now" seems to refer to the removal and taking away of that withered and unfruitful branch, Judas. Christ, in Joh 13:10, had told his disciples, that they "were clean, but not all", because the betrayer was among them; but he being discovered by Christ, and ordered by him to be gone, went out from among them about his wicked design; and now Christ could say of them all, that they were clean: which may be understood of their regeneration and sanctification, in which their hearts were sprinkled with clean water; were washed with the washing of regeneration; had their hearts purified by faith in the blood of Christ, and had pure principles of grace formed in their souls; of all which the Gospel of Christ was the instrumental means: or of their justification by the righteousness of Christ, by which they were justified from all sin; and were all fair, and without spot; which was through the Gospel of Christ revealing his righteousness to them, or through the sentence of justification he, by his Spirit, passed upon their consciences.


Verse 4 Abide in me, and I in you,.... The former of these is an exhortation to continue in the exercise of faith and love upon Christ, holding to him the head, cleaving to him with full purpose of heart, and so deriving life, grace, strength, and nourishment from him; the latter is a promise encouraging to the former; for as Christ is formed in the hearts of his people, he continues there as the living principle of all grace. And so,
as the branch cannot bear fruit of itself, except it abide in the vine, no more can ye, except ye abide in me; which strongly expresses the necessity of abiding in Christ by fresh repeated acts of faith: and it is easy to observe, that when believers depart from Christ, though it be but partially, and for a time, for they cannot finally and totally depart from him, in what a poor, withered, fruitless condition they are, both in their frames and duties.


Ver. 6.
If a man abide not in me,.... Christ does not say, "if ye abide not in me"; he would not suppose this of his true disciples; Judas now being removed, to whom he may have some respect in this verse; though it may be applied to anyone who has made a profession of Christ, and denies the truths of the Gospel, neglects the ordinances of it, or walks unworthy of his profession: of whom the following things may be truly said,

he is cast forth as a branch; that is unfruitful, and is therefore taken away from the vine, and cast forth out of the vineyard. This signifies the ejection of worthless and fruitless professors out of the churches; for such who are either unsound in their principles, or are remiss and negligent in their attendance on the worship of God, with the church, or are loose and vain in their lives and conversations, are to be removed from communion with the people of God.
And is withered. Some versions, as the Arabic, Syriac, and Persic, read this as an epithet of the word "branch", thus; "the branch that is withered"; expressing the condition the branch is in before it is cast forth out of the vineyard, and the reason of its being cast forth: but others read it as a new and distinct predicate of the branch, showing the case it is in, immediately upon its being cast forth: it may be cut off, and cast out with its leaves upon it, though without fruit; but as soon as ever it is ejected, it withers away. So mere external professors of religion, when they are cast out, of the communion of the church, presently the leaf of profession, which once seemed green, decays, loses its verdure, and that seeming fruit which grew upon them shrinks to nothing, and they become "trees whose fruit withereth, without fruit", Jude 1:12: their show of life, zeal, religion, and holiness, disappears, and all their external gifts, light, knowledge, and understanding, even in a speculative way, vanish:
and men gather them; or, as some copies have it, auto, "it", which best agrees with the word "branch". This was a common thing, when branches were thrown out of a vineyard, for men to come and gather them up for an use hereafter mentioned. So when unworthy members are put out of a church of Christ, the men of the world gather them into their society: or they are taken into the congregations of false teachers, who being sensual, and without the Spirit, separate themselves; or it may be read impersonally, "they are gathered", or "it is gathered": so wicked men, and Christless professors, will be gathered by the angels at the last day, and severed by them from the righteous, whom they will place at Christ's left hand to receive their awful doom:
and cast them, or "it",
into the fire, and they are burned, or "it is burned"; for nothing else is such a branch good for; see Eze 15:2. This may respect either the gnawings of conscience, that distress of mind, if not despair, that fearful looking for of judgment, and fiery indignation, which attend apostates in this life; or their being cast into the everlasting burnings of hell fire by angels at the last day, as will be the case of every unfruitful tree, of the chaff and tares.
