Chapter Fifteen
Jn. 15:1. I am the true vine, and My Father is the vinedresser.
What mystery does He teach them? "I," He says, "am the vine, that is, the root, and you are the branches, and My Father is the vinedresser." For whom then does the Father care? Surely for the root? No, but for the branches.
Jn. 15:2. Every branch in Me that does not bear fruit, He takes away; and every one that bears fruit, He prunes, that it may bear more fruit.
For, He says, "every branch not bearing fruit, He cuts off," that is, every person who through faith has become part of the root, has been united with the Lord and made a member of His body, must also bear fruit, that is, lead a virtuous life, so that if someone has only a mere profession of faith, but does not bear fruit through the keeping of the commandments, he becomes a dead branch; for "faith, if it has no works, is dead" (James 2:17).
So then, every believer remains in Christ as long as he believes. "For," He says, "every branch that is in Me, if it does not bear fruit, the Father 'cuts off,' that is, deprives it of communion with the Son, 'but the one that bears fruit He cleanses.'" From this we learn that even a very virtuous person still needs the care of God. For a fruitless branch cannot remain on the vine, while the fruitful one the Father makes even more fruitful.
Understand these words also concerning the tribulations of the disciples. Since tribulations are similar to what gardeners call pruning, the Lord shows the disciples that through tribulations they will become more fruitful, just as branches become through pruning. For through trials they proved to be stronger and stronger.
Jn. 15:3. You are already clean through the word which I have preached to you.
Then, lest they ask, "About whom are You saying this?", He says, "You are already clean through the word which I have preached to you." Look, above He said that the Father cleanses, but now He presents Himself as the one caring for the branches. Thus, the Father and the Son have one activity. "I," He says, "have cleansed you through My teaching: now it is necessary that you too show in deed what is required on your part." Therefore He also adds:
Jn. 15:4. Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, so neither can you, unless you abide in Me.
"I," He says, "have cleansed you through My word and teaching, and on My part nothing has been left unfulfilled. Now your own work must begin."
"Abide in Me." Lest they should separate from Him out of fear, He strengthens their weakened soul, joins them to Himself, and now gives them good hope: "Whatever you ask, you will receive, if you abide in Me" (Jn. 15:7).
Jn. 15:5. I am the vine, and you are the branches; he who abides in Me, and I in him, bears much fruit; for without Me you can do nothing.
By the example of the branch He clearly represents to us that from Him are bestowed strength and life to those who are well-pleasing to Him. For just as that branch bears fruit which abides on the vine and receives from it the assistance for life, so you also, if you abide in Me through the keeping of the commandments, will bear more fruit.
Jn. 15:6. If anyone does not abide in Me, he is cast out as a branch and withers; and they gather such branches and throw them into the fire, and they burn.
And whoever does not abide will "wither," that is, he loses what he had from the root, and if he received any spiritual grace, he is deprived of it and of the help and life communicated from it. And what then in the end? "They are thrown into the fire, and they burn." With these same words He also gives them no small consolation, showing that those who plot against Him, such as Judas, will be burned, while they who abide in Him will bear fruit. For without the power and life-giving energy that are supplied from Him, they will be able to do nothing.
Jn. 15:7. If you abide in Me and My words abide in you, ask whatever you wish, and it shall be done for you.
Here the Lord explains to us what the words "if you abide in Me" mean. Namely: if you keep My commandments. For the words "if My words abide in you" mean that He desires union with them through deeds. For each one who lives in a God-pleasing way abides on the Vine by his own will, being united with It through love and the keeping of the commandments and cleaving to It in spirit; just as, conversely, the one who ceases to keep the commandments voluntarily alienates himself from the Lord.
Jn. 15:8. Glory is given to My Father in this, that you bear much fruit and be My disciples.
"In this," He says, "My Father is glorified, if you bear much fruit." The glory of God the Father consists in the worthiness of the disciples of His Son. For when the light of the apostles shone before men, then they also glorified the Heavenly Father (Matt. 5:14–16). The fruit of the apostles is also those nations which were brought to the faith by their teaching and began to glorify God. And if the Father is glorified when you bear fruit, then He will undoubtedly not neglect His own glory, but will help you bear more fruit, so that He too may be more glorified. My Father is glorified when you bear much fruit "and become My disciples." Do you see? He who bears fruit is a true disciple. And the Father is "glorified" by this, that is, He rejoices and considers this His glory.
Jn. 15:9. As the Father has loved Me, I also have loved you; abide in My love.
He persuades them not to be afraid, and for this reason says: "I have loved you and loved you just as the Father has loved Me." He said this in a human manner. So, "abide in My love" — for this depends on you. And having heard that I have loved you, do not be careless, but strive to abide in My love.
Jn. 15:10. If you keep My commandments, you will abide in My love,
Then He explains how they can abide in this love, namely: if they keep His commandments. For, as has been said many times, he who keeps His commandments loves Him. By all this He shows that they will be safe when they lead a pure life.
Jn. 15:10. As I also have kept My Father's commandments and abide in His love.
