Explanatory Notes on the Whole Bible, by John Wesley, [1754-65], at sacred-texts.com
joh 15:1I am the true vine - So the true bread, Joh 6:32; that is, the most excellent.
joh 15:2Every 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.
joh 15:3Ye are clean - All of you, to whom I now speak, are purged from the guilt and power of sin; by the word - Which, applied by the Spirit, is the grand instrument of purifying the soul.
joh 15:4Abide in me - Ye who are now pure by living faith, producing all holiness; by which alone ye can be in me.
joh 15:5I am the vine, ye are the branches - Our Lord in this whole passage speaks of no branches but such as are, or at least were once, united to him by living faith.
joh 15:6If any one abide not in me - By living faith; not by Church communion only. He may thus abide in Christ, and be withered all the time, and cast into the fire at last. He is cast out - Of the vineyard, the invisible Church. Therefore he was in it once.
joh 15:7If ye abide in me, ye shall ask - Prayers themselves are a fruit of faith, and they produce more fruit.
joh 15:8So shall ye be my disciples - Worthy of the name. To be a disciple of Christ is both the foundation and height of Christianity.
joh 15:9Abide ye in my love - Keep your place in my affection. See that ye do not forfeit that invaluable blessing. How needless a caution, if it were impossible for them not to abide therein?
joh 15:10If ye keep my commandments, ye shall abide in my love - On these terms, and no other, ye shall remain the objects of my special affection.
joh 15:11That my joy might remain in you - The same joy which I feel in loving the Father, and keeping his commandments.
joh 15:12Your joy will be full, if ye so love one another.
joh 15:13Greater love - To his friends. He here speaks of them only.
joh 15:14Ye are my friends, if ye do whatsoever I command you - On this condition, not otherwise. A thunderbolt for Antinomianism! Who then dares assert that God's love does not at all depend on man's works?
joh 15:15All things - Which might be of service to you.
joh 15:16Ye - My apostles, have not chosen me, but I have chosen you - As clearly appears from the sacred history: and appointed you, that ye may go and bear fruit - I have chosen and appointed you for this end, that ye may go and convert sinners: and that your fruit may remain - That the fruit of your labours may remain to the end of the world; yea, to eternity; that whatsoever ye shall ask - The consequence of your going and bearing fruit will be, that all your prayers will he heard.
joh 15:19Because ye are not of the world, therefore the world hateth you - Because your maxims, tempers, actions, are quite opposite to theirs. For the very same reason must the world in all ages hate those who are not of the world.
joh 15:20Joh 13:16; Mat 10:24; Luk 6:40.
joh 15:21All these things will they do to you, because they know not him that sent me - And in all ages and nations they who know not God will, for this cause, hate and persecute those that do.
joh 15:22They had not had sin - Not in this respect.
joh 15:23He that hateth me - As every unbeliever doth, For as the love of God is inseparable from faith, so is the hatred of God from unbelief.
joh 15:25Psa 69:4.
joh 15:26When the Comforter is come, whom I will send from the Father, the Spirit of truth, who proceedeth from the Father, he shall testify of me - The Spirit's coming, and being sent by our Lord from the Father, to testify of him, are personal characters, and plainly distinguish him from the Father and the Son; and his title as the Spirit of truth, together with his proceeding from the Father, can agree to none but a Divine person. And that he proceeds from the Son, as well as from the Father, may be fairly argued from his being called the Spirit of Christ, Pe1 1:11; and from his being here said to be sent by Christ from the Father, as well as sent by the Father in his name.
