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 husbandmantaketh 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 by hlwoyp, and hdwryz. The former, the commentators 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.
