The phrase "you will know them by their fruit" originates from the Bible, specifically from the Gospel of Matthew 7:16-20. Jesus uses this metaphor to teach about discerning true followers from false prophets. The core message is that the true nature of individuals can be identified by their actions and behaviors—analogous to how a tree is identified by the fruit it bears.
"You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles?" (Matthew 7:16 NKJV)
In Matthew 7:15-20, Jesus warns against false prophets who appear harmless but are deceitful at their core. He emphasizes that genuine prophets and followers of Christ will produce good deeds and outcomes, much like a healthy tree produces good fruit. Conversely, despite their outward appearances, false prophets will ultimately reveal their true nature through harmful or deceitful actions. The metaphor is simple yet profound: just as good trees produce good fruit and bad trees produce bad fruit, the true character of individuals is evident in their actions.
True and False Prophets: Matthew 7:15-20
“Watch out for false prophets. They come to you in sheep’s clothing, but inwardly they are ferocious wolves. By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles? Likewise, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus, by their fruit you will recognize them."
The "fruit" in this context represents the visible evidence of one's inner character and spiritual health. Good fruit includes acts of kindness, honesty, integrity, and other virtues that align with Christian teachings. Galatians 5:22-23 lists the fruits of the Spirit, such as love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. These traits signify a life transformed by the Holy Spirit and a heart aligned with God's will.
In contrast, bad fruit includes behaviors and attitudes that contradict Christian values, such as deceit, immorality, greed, and other sinful actions. Jesus' teachings underscore that these negative traits stem from an evil heart, much like how a corrupt tree produces inedible or harmful fruit. False prophets, therefore, can be recognized by their actions that diverge from true Christian teaching and lead others astray.
The Bible provides numerous examples and warnings about discerning false prophets and their fruit. In the Old Testament, prophets like Jeremiah condemned those who falsely claimed to speak for God while leading people into idolatry and sin. Similarly, in the New Testament, Jesus and the apostles warned against false teachers who would emerge within the church, promoting heresies and exploiting believers for personal gain.
Paul's letters to the early churches often addressed the issue of false teachers. In 2 Timothy 3:1-9, he describes them as having a form of godliness but denying its power and advises believers to avoid such people. The emphasis is on the importance of aligning one’s life and teachings with the truth of the Gospel, as true doctrine produces righteous living and spiritual growth.
For modern Christians, the principle of knowing people by their fruit serves as a guide for evaluating spiritual leaders and fellow believers. It encourages discernment and a careful examination of one’s own life and the lives of others. By focusing on the consistent actions and overall character displayed over time, believers can distinguish between genuine and false teachings.
Furthermore, this teaching calls for personal introspection. Christians are encouraged to reflect on their own lives, ensuring that their actions align with their professed beliefs. This alignment strengthens personal faith and serves as a witness to others, demonstrating the transformative power of a life rooted in Christ.
