“Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.” (John 15:8)
The Bible uses agricultural metaphors to describe spiritual reality: some speak of fruitful branches connected to the true vine (Jesus), bringing glory to the Father and proving genuine discipleship (John 15:8), while others warn of land (or lives) that produce only thorns and briers—unfruitful, rejected, near cursing, and destined for burning (Heb 6:8).
Jesus teaches that true character is revealed by what we produce (e.g., Matthew 7:16–20, no grapes from thornbushes). The contrast is stark: fruitful lives reflect connection to Christ and yield good things (love, obedience, character, good works), while thorn-bearing lives show disconnection, barrenness, or harm.
Here’s a good question; who defines what is fruit and what are thorns? That’s the crucial question, isn’t it? In a world full of opinions, subjective morality, and cultural shifts, who gets to decide what counts as good fruit (fruitful, glorifying to God) versus thorns and briers (unfruitful, worthless, harmful, or rebellious)?
Before we look into bearing fruit, let’s answer the question. The Bible warns about human centered standards that lead astray, and produce unfruitful or harmful outcomes.
Who Doesn’t Define GOOD FRUIT?
TRADITIONS of men can never define good fruit (Mark 7:7). Traditions often elevate above or nullify God’s command. The danger is in the possibility of practicing vain worship that cannot honor nor glorify God.
HEART (“It feels right to me”) “The heart is deceitful above all things, and desperately wicked: who can know it?” (Jeremiah 17:9). The danger lies in self-deception; what “feels good” can justify sin or error, yielding thorns of pride and rebellion instead of humble submission to God’s revealed will. Our feelings never override God’s word.
OPINIONS of men or of the majority. Naaman is a perfect example of this. Despite his terrible condition, his opinion about how it was to be done turned him in a rage away from the cure. “I thought… Are not Abana and Pharpar, rivers of Damascus, better than all the waters of Israel? may I not wash in them, and be clean? So he turned and went away in a rage” (2Kings 5:11-12). The danger lies in following hapless & happy ignorant mobs into destruction, (Matt 7:13-14; 15:14).
RELIGIOUS performance to be seen of men. Jesus highlighted those who practiced their religion to “be seen of men” (Matt 23:5-7; 6:2,5,16). He went onto say, “Verily I say unto you, They have their reward.” The danger lies in that showmanship never produces lasting fruit. Kudos from men is a lousy reward (Galatians 1:10).
NICE in appearance masks the rotten fruit. Paul warned repeatedly about masquerade parties. “And no marvel; for Satan himself is transformed into an angel of light” (2Cor 11:14; 2Pet 2:1-3; Acts 20:29-30). The danger is in the subtle seduction of charming exteriors that hides the destructive heresies, leading souls astray.
SEASONAL TRENDS shift like winds. “That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine” (Ephesians 4:14). Fads come and go, but the word of the Lord endures forever (1Peter 1:24-25). Chasing novelties yields fleeting, unprofitable results rather than enduring fruit rooted in Christ’s truth. The danger is immaturity and instability.
Good fruit is defined solely by God’s revealed Word. Relying on unreliable sources risks producing thorns (worthless, harmful growth) that leads to rejection. Abide in the doctrine of Christ alone for fruit that glorifies the Father.
