When people hear "works" or "fruit," many immediately worry about adding to Christ’s finished work on the cross. That fear is understandable; and the Reformation rightly fought against any such notion that we can earn our salvation. But the works the gospel and New Testament talks about are not additions; they are extensions and evidence of Christ’s work in us.
The faith itself is absolutely a gift:
Ephesians 2:8-9
"For by grace you have been saved through faith; and this salvation is not of yourselves, it is the gift of God; not a result of works, so that no one may boast."
And likewise, the desire and power to obey are also from God:
Philippians 2:12-13
"for it is God who is at work in you, both to [be willing] desire and to work for His good pleasure."
Ezekiel 36:26-27
"Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. And I will put My Spirit within you and bring it about that you walk in My statutes, and are careful and [do] follow My ordinances."
Therefore, even our best works cannot be a ground for our boasting about ourselves; they are Christ’s fruit working through us, a continuum of His ongoing grace.
This is what's meant by Jesus' use of the metaphor about the vine:
"I am the vine, you are the branches; the one who remains in Me, and I in him [this one] bears much fruit, for apart from Me you can do nothing." (John 15:5)
This is why James can say, "Faith without works is dead" (James 2:17) and Paul can insist we are saved by grace through faith, not works (Ephesians 2:8-9). They are not contradicting each other. One guards the root (grace), the other examines the fruit.
In my landscape at home I have many examples of this dichotomy. Imagine a healthy apple tree. I have several varieties in my yard. One of my favorites is "Liberty".
The Liberty Apple tree's rootstock is hidden underground. It draws water, nutrients, and life from the soil. Without this strong, living root, the whole tree eventually dies. This is grace; the unseen, life-giving work of Christ. We are saved by grace alone, through the faith root alone. Nothing we do adds to or earns that root giving connection.
The fruit hangs on the branches above, for everyone to see. Crisp, beautiful Liberty apples that DO NOT create the tree; they are the natural, seasonal result of a healthy productive tree. And you can examine the fruit to know whether the root is alive and strong. This is works/obedience/distinctive lifestyle; the visible evidence of genuine faith. James examines the fruit (the Spiritual gift of discernment). Paul guards the root (the Spiritual gift of faith).
Now here's where it gets under peoples skin.
A tree that never produces apples (or produces only small, diseased wormy ones) is either dead, infected, diseased, or planted in poor soil. Even if the trunk looks impressive for a while. But the apples themselves don’t make the tree alive; they prove the root already is alive and they also prove the rotten fruit.
See, the thing is, this Liberty apple tree (the above ground parts) is grafted to specially produce a particular type of apple (the fruit). It was designed to perfectly and consistently produce this hybrid fruit. And in addition, it is grafted onto a rootstock that was specifically chosen and designed to support this particular hybrid scion. The rootstock and the scion share a nature (apple tree nature) but they are not 100% alike. The rootstock is vigorous, strong and fast-growing and alone it produces its own sort of apple. But when the scion is selected and grafted to the rootstock, everything below the ground (below the graft) remains rootstock and everything above the ground becomes Liberty (scion). Both at work together, but Liberty will absolutely die without the rootstock. And without Liberty, the rootstock goes on, sovereign, eternal, and pure in its own nature.
In the same way, when we are grafted into Christ the true Vine, we are united with Him in a living, organic connection. The root is grace; strong, eternal, and life-giving. The fruit is the natural result of that union. We share in His nature, yet we remain utterly dependent on Him. Apart from Him we can do nothing (John 15:5). The life flows from the root; (and here's the notable part) the fruit reveals whether the graft "took."
There's this thing called a "bad graft", where the union doesn’t take properly. The tree may look okay for a season, but it eventually fails to produce good fruit, or the scion withers. Typically, there's a poor cambium connection that allows disease and insect infestation to get in-between the root and the scion. Then, in time, it weakens the connection until finally it fails. And one of two things typically happens. Either it weakens so much that it rots and breaks clean off, or it is cut off by the rootstock itself.
Jesus warns us about this very reality in Matthew 7. Many will say to Him on that day, "Lord, Lord," and even point to impressive-looking works done in His name. Yet He will declare, "I never knew you; depart from Me, you who practice lawlessness" (Matthew 7:21-23). In those cases the rootstock is no longer providing life-giving support, and the scion eventually withers and is cut off. The outward appearance may have looked impressive for a season, but the lack of lasting fruit revealed the truth; the graft never truly took. All foliage, no fruit. Lots of beautiful leaves, and even pretty apple blossoms, but nothing comes of it all.
So what does this mean for us today?
Examine the fruit (be James for just a moment), not to earn salvation, but to make sure the graft has truly taken.
If the Spirit is truly at work in you, He will produce a desire and power to live differently.
To love when it’s hard, to serve when you’d rather be lazy and self-focused, to honor authority, love God and to show compassion like Jesus.
Don’t settle for impressive-looking foliage. Abide in the Vine daily. Let the life of Christ flow through you so that real, lasting fruit appears. Attract pollinators (metaphor for evangelism) go and preach/teach the word. All for His glory and the good of those around you. Faith is still not alone.
