Trinity 20…Oct. 18, 2026…John 15:1-8…Are You Fruitful Branches of the Vine?

¹ “I am the true vine, and My Father is the vinedresser. ² “Every branch in Me that does not bear fruit He takes away; and every branch that bears fruit He prunes, that it may bear more fruit. ³ “You are already clean because of the word which I have spoken to you. ⁴ “Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me. ⁵ “I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing. ⁶ “If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned. ⁷ “If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you. ⁸ “By this My Father is glorified, that you bear much fruit; so you will be My disciples.

Grace, mercy, and peace be yours from God our Father and our Lord and Savior Jesus Christ, Amen.

INJ who is the life-giving vine, the worker of all good things within us, DFR:

According to a 7 year study done by a coalition of European agricultural researchers, there is a dramatic difference between pruning a vineyard and not pruning a vineyard. They found that the unpruned vineyard produced 30% higher fruit yields than the pruned vineyard. However, the larger quantity meant much smaller grapes and a longer maturity delay than the pruned vineyard. And, despite the high yield, the unpruned vineyard revealed the high quantity of grapes to be unsustainable and, in the long term, proved to be worse for the production of fruit than pruning the vineyard.

You don’t need a 7-year scientific study to know the importance of pruning any fruit-bearing vine, including Jesus who shows the Kingdom of God requires fruit through this illustration. This morning we ask ourselves the very simple question: Are you a fruitful branch of the Vine? Yes, when you abide in the true Vine. Yes, when you bear much fruit to the Father’s glory. May the Holy Spirit bless our study of His Word this morning.

In the first three verses, Jesus lays out the basic facts of this illustration. He is the true Vine, the Father the vinedresser, and you and I are the branches. The fruit referenced is the fruits of the Spirit as Paul describes in Galatians 5:22-23, “the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, ²³ gentleness, self-control.” From the beginning, it was God’s desire to have His people be like a vineyard that He would tend to bear this fruit.

The Children of Israel were a vine shadow of Jesus. God brought the nations to Israel in order to hear the promise of a Savior and find salvation. Think of Naaman whom Elijah healed of leprosy, or Rahab and Ruth as branches of the Israelite vine. But there was a problem with Israel being the vine. They were rotten at the core. The Children of Israel had sinful natures just like you and me, that rebel against God, hate His commandments and rejected the promises of God that were their very life-source.

Nothing good comes out of a diseased vine. That is why God, in His divine wisdom, did not make Israel the true vine. Jesus set Himself apart as the true Vine because only He could accomplish God’s gracious purpose and will – fulfilling the Law perfectly and offering up His life as a sacrifice for sin. Jesus is the true Vine because only He can produce life and only through Him can we, the branches bear fruit that brings glory to God.

² “Every branch in Me that does not bear fruit He takes away;

If Christ is the vine, and His disciples are the branches, how is it that there can be those who bear no fruit? To be a branch of Christ means to partake of His life and spirit – to believe in Him for life and salvation. There are many who have known Christ, tasted His love, but have forsaken the true Vine and become a wild shoot, a dead branch, and have lost all fruitfulness. Think about Judas Iscariot who was Jesus’ disciple, but even as Jesus spoke these words, was betraying his Lord.

The sad reality comes in verse 6:“If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned. It all comes down to bearing fruit – not because fruits of faith save you, but because they show that you abide in Christ even as He abides in you. It’s never a question of Jesus’ willingness to abide in you – He is always willing to abide. The problem is with you and me and our unwillingness to abide in Christ. Think about how spiritual life withers away: “I don’t need church, I have a personal relationship with God;” then, “I can do pretty good on my own, I already know what God says;” “I’ll pick up my Bible later, I have more important things to get to.” And pretty soon, their hearts are seduced away from Christ and the power of His death to the point that they bear no more fruit.

The final judgment for such branches is absolute. The wood of the vine branches is fit only for one of two things, to bear fruit or to burn. What branch are you? I think we all know, that by nature we deserve to burn under God’s judgment. How frail our fruit has been! How weak our willingness to abide in Christ rather than our flesh!

Jesus’ words here are necessary. They prick at our flesh and might make us feel uncomfortable, but without them, we lose sight of how seriously God takes sin. We may treat sin like it’s not that big of a deal. Or that regular attendance to hear His Word and receive His Sacrament is unnecessary. To God it is a big deal. Sin is what separates us from Him. Sin is what makes us dead by nature so that we cannot bear fruit by ourselves. Sin is what necessitated Jesus’ suffering and death. God wants to show mercy, but first He must condemn sin.

³ “You are already clean because of the word which I have spoken to you. ⁴ “Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me.

The word Jesus speaks of is the Gospel. It is the message of God’s undeserved love for sinners like you and me – who can do no good thing on their own, but who were dead in our trespasses and sins. God loved you despite of your animosity towards Him. He sent Jesus in spite of knowing how He would be treated, persecuted, and killed. God’s love gave an answer to your sin. Jesus’ grace has made it so that you do not have to fear God’s judgment. You are not in danger of being thrown into the fire because you are attached to the true Vine.

And that is when we come to this precious word “Abide.” This word denotes an active, continual residence in once place. If Jesus just commanded “Abide in Me,” it would make our hearts sink because we cannot. But no, Jesus includes, “and I in you.” Jesus willingly makes His home in your heart through faith. To abide in Christ is to continue believing in Him, to keep on receiving from Him grace for grace, day by day, in ever greater fulness, and He makes it possible.

Jesus is the true Vine that gives you life. He is responsible for your development and growth – feeding your faith through the preaching of the Word and administration of the Sacraments. For these convey to us His grace and gifts. “Abide in Me” is a true Gospel command because Jesus loves to give. You cannot separate “Abide in Me and I in you” – You cannot be separated from Christ. His home is in your heart and Jesus always works from home. Take what He is giving – the forgiveness of sins and the promise that He will abide in you so that with Him you may produce abundant fruit.

For those branches that have broken off and are withering? There is hope for them in the true Vine. Jesus’ heals all to those who believe in Him for salvation. Are you a fruitful branch of the Vine? You are when you abide in the true Vine, for then you have life. But we are called to be more than just to be connected to the Vine, we are to also bear much fruit.

…every branch that bears fruit He prunes, that it may bear more fruit. What comfort it is that our heavenly Father is the vinedresser. It is His responsibility and purpose to prune the branches with the purpose to bear even more fruit. The fruit that is produced in every believer’s heart is a direct result of Jesus’ saving work because it is His love which led Him to the cross that changes your heart to love as He would have us love; to find joy in the forgiveness of sins, have the same peace with others as we have with God through Christ; to be slow to anger, love righteousness and truth and avoid what is evil.

This fruit might be little and often, there should be much more. But so long as there is any drawing of life from Christ, there will be this fruit. The Vinedresser, our heavenly Father, has such great concern about this fruit that His divine working is in this direction to produce more.

What does the Father prune off? All that remains of our old sinful nature, the flesh and its manifestations and growths. These must be taken away and are, by the Father so that the fruits of the Spirit thrive and grow abundant. Our Lord and the Apostles admonish, reprove, rebuke, and warn us constantly against the workings of the flesh. When you prune a branch, does it not appear to hurt the branch, but you know it is to make it healthier? So also God’s Word must cut deep into our hearts that the spirit of grace may constantly triumph over the flesh and bring forth fruit right for repentance.

Even as Paul says in 2 Corinthians 4:16, ” Therefore we do not lose heart. Even though our outward man is perishing, yet the inward man is being renewed day by day.” Day by day God’s mercies are new. Not only to forgive us our sins, but to strengthen the connection to the Vine that is Christ for He works in us to will and to do according to His good pleasure.

How much care the great Vinedresser has for His branches! He does not let us rot and inevitably leave the Vine that gives us life. He prunes and restores through His Word to not only give strength, but to increase opportunity and desire to bear more fruit! Why should we ever be satisfied with a few ill-formed clusters of fruit, when we ought to bear many of the very finest of kinds! Luther reminds us, “This life is not that we are pious, but that we become pious; not a rest, but exercise.”

The greatest treasure is that the fruit we bear brings glory to Him who saved us. What higher reason do we need to abide in the true Vine! May we prove to be Jesus’ disciples by abiding in His Word, bearing fruits of the Spirit in our lives and give all glory and honor to God our Father. As we will sing in a few moments:

O God, forsake me not! Thy mercy I’m addressing; O Father, God of Love, Grant me Thy heavenly blessing To do when duty calls Whate’er Thou didst allot, To do what pleaseth Thee– O God, forsake me not! Amen.
