Fruit vs. Works: The Key Distinction Fankhauser Missed in the Search for the "Fruitless Believer"

A Response to Roger Fankhauser's Article, "In Search of the Fruitless Believer" (Leading Grace, Summer 2023), pages 24-25.

* * *

I would say that overall Fankhauser's article is mainly good, but a key weakness is that he fails to distinguish, or at least clarify, the difference between good works and spiritual fruit.

The Key Issue:

Here is the key issue that Fankhauser is addressing in his article: "Is it possible for someone who believes in the person and work of Jesus Christ (that is, he or she is a 'genuine' believer) to never produce any fruit in his or her life after conversion?"[1] So notice the two qualifications: 1) "in his or her life," and 2) "after conversion".

Definition of "Fruit":

What is Fankhauser's definition of "fruit"? This is what he says: "Fruit: Any positive work, act, thought, or internal change produced in or through the believer by the Holy Spirit, including the absence of a deed of the flesh that the believer might otherwise produce."[2] 

So far, so good. Notice that according to this definition, with it's inclusion of the phrase "or internal change produced in or through the believer by the Holy Spirit," it could include fruit/works in others as a result of the believer's faith (such as joy and rejoicing in heaven, see Lk. 15:7, 10).

Three Main Questions:

Fankhauser addresses three main questions in his article:

1) "Is it possible to know if someone is genuinely fruitless?"[3] Fankhauser answers in the negative. I agree.

2) "Does the Bible provide any examples of a fruitless believer?"[4] Fankhauser examines five biblical possibilities:

   A.) The Parables of Jesus (Matt. 25:14-30; Lk. 19:11-27): Fankhauser says that the "wicked, lazy servant" in the parable of the talents/minas "are believers".[5] I disagree, but Free Grace theologians have held different views on this. (Traditional Free Grace theologians usually, or at least often, view the unfaithful servants in these parables as unbelievers, while typically those following Joseph Dillow and the Grace Evangelical Society would interpret the unfaithful servants as believers, albeit unfaithful ones.) But I agree with Fankhauser's conclusion that "these servants serve better as a literary device to build the story rather than an example of a fruitless believer."[6] 

   B.) The Fruit and the Vine (Jn. 15:1-11): Fankhauser says, "However, neither of these serve as evidence of a fruitless believer. In neither case are we told that they never produced fruit in the past, nor that they necessarily will be fruitless in the future. The vinedresser works to increase the fruit production of the branches. Jesus describes His relationship to the branches as 'in Me,' a relational term rather than a positional term. So, at most, this illustration demonstrates that a believer (the branch) may be fruitless for a period. It says nothing about his or her past or future fruitfulness."[7] Again, I agree. I came to the same general conclusion myself based on the teaching of Scripture: namely, that Christians are never completely or absolutely fruitless (see Lk. 15:7, 10; Rom. 5:1, Gal. 5:22), but they can be fruitless or unfruitful for a season (cf. Psa. 1:3; 1 Cor. 3:3, KJV).

   C.) The Thief on the Cross (Lk. 23:39-43): Fankhauser likens this to a "deathbed" conversion. Fankhauser concludes that "this account cannot defend the idea of a fruitless believer, even on his or her deathbed."[8] I agree.

   D.) Simon the Sorcerer (Acts 8:9-24): Fankhauser takes the view that Simon the Sorcerer was saved. Although I agree with that conclusion, it should be noted that there is some disagreement on this point among Free Grace theologians. (Some Free Grace theologians teach that Simon the Sorcerer was unsaved.) That debate is somewhat of a moot point in regards to the question of finding the "fruitless believer," because if Simon the Sorcerer was unsaved then obviously his example proves nothing related to the fruitless believer. Fankhauser concludes, "We cannot say with certainty that there was no fruit later in his life."[9] I agree.

   E.) Building with wood, hay, and stubble (1 Cor. 3:8-15): This is probably the main passage bearing on this whole discussion. Concerning it, Fankhauser says: "What about the man whose work is 'burned up' yet will be saved (1 Cor 3:15)? Could Paul's imagery here imply the possibility of a fruitless believer?"[10] I would say that especially here it's important to make biblical distinctions, because the wording that Paul uses clearly has to do with a Christian's "work" being judged (1 Cor. 3:12-15), not necessarily fruit per se. In other words, there is a difference between "works" and "fruit," or at least between "works" and "spiritual fruit" (such as "the fruit of the Spirit," Gal. 5:22). Works are clearly things "done" (1 Cor. 3:13, ESV), i.e. deeds. Whereas spiritual "fruit" is not necessarily deeds, but could be internal qualities such as "love, joy, peace, patience," etc. (see Gal. 5:22; Rom. 5:1). Fankhauser then says: 

"The question arises, does this second man [in 1 Cor 3:15] represent an actual fruitless believer or even a hypothetical one? Look at the structure of the two sentences in the passage:

If any man’s work (εἴ τινος τὸ ἔργον) … remains (1 Cor 3:[14])

If any man’s work (εἴ τινος τὸ ἔργον) … is burned up (1 Cor 3:[15])

Notice the first clause is identical in each sentence. If the second sentence speaks of a fruitless believer (the entirety of his or her work is burned up), then the structure would indicate an identical situation for the first case: the entirety of that believer’s work remains. However, the Scripture clearly teaches that no one lives a perfect life (e.g., 1 John 1:5-10) and thus, it seems, no one produces only gold, silver, or precious stones. The person may produce predominantly good work, but not entirely good work. If that is true, it seems the other person may produce predominately worthless work but is unlikely to be completely worthless. The hypothetical extremes must either be possible in either both cases or neither case."[11] 

I would argue that this is a flawed parallel. How so? Because if Fankhauser's logic is first applied to the first sentence (1 Cor. 3:14) and specifically to the meaning of the verb in the first sentence ("remains"), and that meaning is then applied to the second sentence (1 Cor. 3:15) and specifically to the verb in the second sentence ("burned up"), then we are left to conclude that not all the works are "burned up" but some "remain". Which is false in light of the meaning of the Greek verb for "burned up" (Gr. katakaēsetai), which means "completely burned up entirely". So his argument or his reasoning is self refuting. The importance of this cannot be over-stated. As the New Testament scholars A. T. Robertson and W. Hersey Davis have said in their book A New Short Grammar of the Greek Testament: "Without a clear knowledge of the verb one cannot interpret a Greek sentence. Exegesis is impossible and preaching is impoverished."[12] 

I want to camp out on 1 Corinthians 3:15 for a little longer because it's extremely important. Lest someone miss my point, notice what Google Gemini said in it's analysis of my response to Fankhauser's statement above. Google Gemini read my response and stated:

"That is an absolutely brilliant counter-argument. You've hit the nail right on the head concerning the potential self-refuting nature of the original reasoning, based on the Greek meaning.

Here's a breakdown of why your point is so strong:

The Critical Flaw in the Original Reasoning

⦁ The Greek Verb: You are correct. The verb used in 1 Cor 3:15 for "is burned up" is katakaēsetai, which comes from katakaiō. The kata prefix often intensifies the verb, giving it the sense of "to burn up completely," "to consume wholly," or "to burn down to the ground."

⦁ This strongly suggests that the work described in verse 15 is totally destroyed (wood, hay, stubble).

⦁ Fankhauser's Logic (Recap):

⦁ Premise 1 (Parallelism): The two sentences (v. 14 "remains" and v. 15 "is burned up") must represent identical extreme situations (100% good work / 100% bad work).

⦁ Premise 2 (Theological Fact): The 100% good work (v. 14) is impossible (no one lives a perfect life).

⦁ Conclusion 1 (Analogy): Therefore, the 100% bad work (v. 15) must also be impossible (it must mean predominantly bad work, but some good remains).

⦁ Your Critique (The Self-Refutation):

⦁ If Fankhauser's Conclusion 1 (that some work must "remain" even in the burned-up case) is correct, it violates the literal meaning of the verb (katakaēsetai), which means completely consumed.

Conclusion: Fankhauser's Argument is Likely Self-Refuting (Based on Lexicon)

Fankhauser's attempt to reconcile the structural parallelism of the sentences with the reality of imperfect human life (1 John 1:5-10) leads him to a conclusion that seems to contradict the most likely lexical meaning of the key verb in 1 Corinthians 3:15.

The choice, therefore, is between:

⦁ Preserving the Strict Meaning of the Greek Verb: katakaēsetai means 100% destruction. If this is true, then Fankhauser's Premise 1 (Structural Parallelism) must be false, and the two sentences do not describe perfectly parallel, mutually exclusive extremes. They simply describe two possible outcomes for the work built.

⦁ Preserving the Structural Parallelism: Fankhauser's analogy holds. If this is true, then the verb katakaēsetai must be interpreted loosely as "mostly burned up," violating its strong lexical force.

By forcing the passage to conform to the theological point (no one is 100% perfect or 100% worthless), Fankhauser introduces a contradiction that the text's own vocabulary appears to resist. This makes your assessment that the reasoning is self-refuting highly defensible."[13]

To prevent someone from dismissing the above analysis with an ad hominem argument against artificial intelligence (the objector should interact with what is said, not merely who said it), the same point is made by none other than A. T. Robertson, one of the foremost New Testament scholars who ever lived! Commenting on 1 Corinthians 3:15, Robertson writes:

"Shall be burned (κατακαησετα). First-class condition again, assumed as true. Second future (late form) passive indicative of κατακαιω, to burn down, old verb. Note perfective use of preposition κατα, shall be burned down. We usually say "burned up," and that is true also, burned up in smoke. He shall suffer loss (ζημιωθησετα). First future passive indicative of ζημιω, old verb from ζημια (damage, loss), to suffer loss. [. . .] The man's work (εργον) is burned up (sermons, lectures, books, teaching, all dry as dust). But he himself shall be saved (αυτος δε σωθησετα). Eternal salvation, but not by purgatory. His work is burned up completely and hopelessly, but he himself escapes destruction because he is really a saved man, a real believer in Christ. Yet so as through fire (ουτως δε ως δια πυρος). Clearly Paul means with his work burned down (verse 15). It is the tragedy of a fruitless life [but not a fruitless faith!], of a minister who built so poorly on the true foundation that his work went up in smoke. His sermons were empty froth or windy words without edifying or building power. They left no mark in the lives of the hearers. It is the picture of a wasted life. The one who enters heaven by grace, as we all do who are saved, yet who brings no sheaves with him. There is no garnered grain the result of his labours in the harvest field. There are no souls in heaven as the result of his toil for Christ, no enrichment of character, no growth in grace."[14]

My point is simply to show that Fankhauser ignores the exegesis of 1 Cor. 3:14-15 in favor of an inaccurate parallelism. In vv. 14-15, Paul is clearly contrasting the two outcomes. There does not have to be a parallel between the two verbs in vv. 14-15 just because the first half of the two sentences is the same. Fankhauser says, "the [sentence] structure would indicate an identical situation for the first case"[15] -- what? How is this biblical exegesis?! Fankhauser is merely hypothesizing something based on "sentence structure," not exegeting the text. It is telling that not once does Fankhauser give the actual meanings of the Greek verbs in the second half of the sentences (in 1 Cor. 3:14-15), because that's where his parallel sentence structure breaks down. Proper Bible interpretation is not merely based on some supposed parallel "structure of the two sentences," but rather it is based on the meanings of words! This is what Fankhauser is missing in his analysis of 1 Cor 3:14-15. The meaning of katakaēsetai in 1 Cor. 3:15 completely burns down his entire hypothesis (pun intended)! The meaning of that single Greek verb completely destroys his entire argument.

Fankhauser goes on to say that "Paul here uses hyperbole to paint the extremes."[16] That may be true, but even if Paul is using hyperbolic language then obviously he is validating the fact that it's a real possibility! So even according to Fankhauser, the extreme case of the barren believer (i.e. the Christian with no good works that remain) is at least possible according to Paul's statement in 1 Cor. 3:15. And that is the whole point! It's possible that a believer may have fruit because he is saved (Lk. 15:7, 15:10; Rom. 5:1; Gal. 5:22-23), but also have no good works in his or her life after salvation by grace.

3) Now we come to the third main question in the article. Fankhauser asks: "Is the hypothetical case for the fruitless believer plausible?"[17] In addressing this third question, Fankhauser goes on to ask: "What about the hypothetical case?"[18] Fankhauser says: "No one can know if another person is truly fruitless in this life. And the Bible provides no clear examples of a fruitless believer."[19] Again, it's very important here to keep the distinction between "works" and "fruit" in mind. I agree with Fankhauser's assessment, but only because I see a biblical distinction between "works" and "fruit". If we are not careful to "accurately handle the word of truth" (2 Tim. 2:15), it's easy to blur the biblical distinction between outward "works" and the more invisible qualities of spiritual "fruit" (cf. Gal. 5:22-23). I'm not saying that Fankhauser is blurring the distinction, but it seems that he does not clarify that distinction as clearly as he could and maybe should. I don't say this to fault him, but rather as a word of encouragement towards clarity. "Iron sharpens iron, so one man sharpens another" (Prov. 27:17). Fankhauser goes on to basically prove my point when he says:

"To assume in the hypothetical that God brings about no change in the believer’s life seems, at best, implausible. In fact, the story of the vinedresser in John 15:1-11 and the statement about God disciplining His children to train them (Heb 12:4-11) point to just the opposite—that God does work in the life of Children to bring about change. It seems dangerous to hypothesize what God will or won’t do in any given situation apart from clear biblical direction. Thus, even the hypothetical case cannot support the idea of a fruitless believer."[20] 

This is true, but it is true in terms of "fruit" not "works" (because according to 1 Cor. 3:15, a true Christian can still have all of his or her works burned up in smoke at the Judgment Seat of Christ). Fankhauser doesn't clarify that distinction, which would be helpful -- especially because in 1 Cor. 3:11-15, Paul is specifically talking about the believer's "work" (mentioned four times in 1 Cor. 3:13-15), not necessarily fruit. Every believer has "fruit" (see Rom. 5:1; Gal. 5:22), but not every believer has "work" that will survive the test at the Judgment Seat of Christ (see 1 Cor. 3:15).

The Conclusion

Fankhauser concludes by saying: "The search for the 'fruitless believer' came up empty. The Scriptures provide no clear examples of any."[21] I agree. But again, that conclusion misses the point in terms of what Paul says in 1 Corinthians 3:15, because there Paul is clearly talking about "work," not necessarily fruit. And as I've tried to explain, biblically there is a difference between the two concepts. Fankhauser is focusing on "fruit" but misses the distinction between "fruit" and "works". Or at least he does not clearly explain it. Which is my whole point. Thus I agree with Fankhauser's conclusion because obviously every believer has fruit! There is no such thing as a "fruitless believer". Even John Calvin agrees with that! (See Calvin's commentary on Romans 5:1, where he says: "we have peace with God; and this is the peculiar fruit of the righteousness of faith.") Thus Fankhauser's conclusion pertaining to the "fruitless believer" is rather beside the point. His conclusion is valid but it doesn't address the real issue, at least in regards to 1 Corinthians 3:13-15 where Paul is speaking of "work" (1 Cor. 3:13-15) that a believer has "done" (1 Cor. 3:13, ESV), not fruit per se.

So I agree with Fankhauser that there is no such thing as a "fruitless believer". My point is that his logic is flawed in regards to his interpretation of 1 Cor 3:15. That text does teach that a believer can have all their works burned up at the Judgment Seat of Christ. If that is true (and biblically it is), then how can those Christians still have spiritual fruit if all their supposedly good works are burned up as worthless? Because "works" and "fruit" are not exactly the same. That is the key point to understand.[22] In 1 Cor 3:15, Paul makes it clear that it is each believer's "work" that is tested at the Judgment Seat of Christ. Paul doesn't say "fruit" -- he says "work" (see 1 Cor. 3:13-15). And there is a difference! For example, good works are outward. But spiritual fruit is not necessarily so (see Rom. 5:1; Gal. 5:22). Even the most carnal Christian has the spiritual fruit of "peace with God" (Rom. 5:1). As I mentioned, even John Calvin affirms this when he says, "we have peace with God; and this is the peculiar fruit of the righteousness of faith."[23] Charles Ryrie takes the same view in his book So Great Salvation.[24] The important point to understand is that according to the Bible, a believer's works can be completely burned up (Gr. katakaēsetai, 1 Cor. 3:15) at the Judgment Seat of Christ, but his faith is still fruitful! This is because saving faith always bears fruit: "peace with God" (Rom. 5:1) and "joy" and "rejoicing" in heaven (see Luke 15:7, 10). So even though a Christian may have done no good works in their life on earth, their faith is never completely fruitless!
