John 15:2

“Every branch in me that beareth not fruit, etc.] 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,…”

“Every branch in me that beareth not fruit . . . every branch that beareth fruit--As in a fruit tree, some branches may be fruitful, others quite barren, according as there is a vital connection between the branch and the stock, or no vital connection; so the disciples of Christ may be spiritually fruitful or the reverse, according as they are vitally and spiritually connected with Christ, or but externally and mechanically attached to Him. The fruitless He "taketh away" (see on Joh 15:6); the fruitful He "purgeth" (cleanseth, pruneth)--stripping it, as the husbandman does, of what is rank (Mar 4:19), "that it may bring forth more fruit"; a process often painful, but no less needful and…”

“Every branch in me - Everyone that is a true follower of me, that is united to me by faith, and that truly derives grace and strength from me, as the branch does from the vine. The word “branch” includes all the boughs, and the smallest tendrils that shoot out from the parent stalk. Jesus here says that he sustains the same relation to his disciples that a parent stalk does to the branches; but this does not denote any physical or incomprehensible union. It is a union formed by believing on him; resulting from our feeling our dependence on him and our need of him; from embracing him as our Saviour, Redeemer, and Friend. We become united to him in all our interests, and have common feelings,…”

“Every one that beareth fruit, he purifieth - by obeying the truth, Pe1 1:22; and by inward or outward sufferings, Heb 12:10-11. So purity and fruitfulness help each other. That it may bear more fruit - For this is one of the noblest rewards God can bestow on former acts of obedience, to make us yet more holy, and fit for farther and more eminent service. John 15:3”

“15:2-3 Gardeners cut away dead branches and trim healthy branches so they will produce more fruit. Fruitfulness is the result of life-giving connection to the vine.”
