Matthew 7

Verses 15–20 WEB Voices

On the narrow way, Jesus warns of false prophets: charming exteriors, predatory hearts, and a simple test—fruit over fleece. Disciples must discern by what a life and teaching actually produce.

Matthew 7:15

15“Beware of false prophets, who come to you in sheep’s clothing, but inwardly are ravening wolves.

Arminian

“Beware” is pastoral alertness, not paranoia. False prophets look like sheep—familiar, religious, even comforting—yet inwardly they devour. Appearance is not enough; character and teaching must be tested.

Arminians hear a call to responsible discernment. Grace does not replace vigilance; it enables it. Both note: the flock needs protection from wolves dressed as helpers.

Reformed

Jesus assumes the church will face deceivers. Sheep’s clothing names the danger of religious camouflage; wolves name the intent to consume.

Christ shepherds His people by Word and Spirit. Beware is covenant care—He warns so that His sheep will not be naive about counterfeit voices.

Matthew 7:16

16By their fruits you will know them. Do you gather grapes from thorns or figs from thistles?

Arminian

Fruit is the public test. Grapes do not grow on thorns; figs do not come from thistles. Over time, teaching and life reveal the tree. Discernment is patient and concrete.

You can and should learn to recognize fruit. Grace sharpens sight; believers are responsible not to excuse bad fruit for the sake of impressive fleece.

Reformed

Recognition by fruit is Jesus’ appointed criterion. Nature produces after its kind; so do prophets. Rhetoric and costume cannot permanently hide a thornbush heart.

Fruit includes doctrine and life under the Word. The test protects the church from charm without truth and truth-claims without holiness.

Matthew 7:17

17Even so, every good tree produces good fruit, but the corrupt tree produces evil fruit.

Arminian

Healthy and diseased trees differ in what they produce. Jesus ties inner condition to outward result. Good fruit is expected from a sound tree; bad fruit exposes disease.

Classical Arminians stress that grace renews the tree so that good fruit becomes possible and actual. Holiness is not optional decoration; it is evidence of a living faith.

Reformed

The proverb is moral and spiritual: trees bear according to their nature. A healthy tree’s good fruit and a diseased tree’s bad fruit are not accidents.

New birth makes a healthy tree. Good fruit is the Spirit’s produce, not a ladder by which we climb into favor—yet fruitlessness remains a grave warning.

Matthew 7:18

18A good tree can’t produce evil fruit, neither can a corrupt tree produce good fruit.

Arminian

Jesus speaks in strong cannot-language about settled natures. Habitual bad fruit contradicts a claim of health. The saying presses honesty about what our lives keep producing.

If fruit is bad, seek the Physician. Grace can heal a diseased tree; denial only prolongs harm to self and flock.

Reformed

Cannot marks incompatibility of natures. Counterfeit goodness may mimic for a time; the settled yield of a diseased tree is bad fruit.

Regeneration changes the tree. Where Christ makes healthy, good fruit follows—imperfect yet true—because the Spirit does not leave His work barren.

Matthew 7:19

19Every tree that doesn’t grow good fruit is cut down and thrown into the fire.

Arminian

Judgment language is clear: fruitless trees face fire. Jesus warns to awaken, not to entertain despair. The axe and fire call for repentance while there is time.

Heed the warning; turn and bear fruit worthy of repentance. Grace invites change before the cutting comes.

Reformed

Eschatological seriousness: unfruitful trees are cut down and burned. Jesus echoes John the Baptist’s axe at the root—kingdom judgment is in earnest.

Final judgment vindicates the difference fruit reveals. The warning belongs to the gospel’s honesty; the remedy is Christ, who makes trees alive.

Matthew 7:20

20Therefore by their fruits you will know them.

Arminian

The section closes where it opened: recognition by fruits. Disciples are not left guessing; they are given a workable, pastoral test.

Practice fruit-watching with humility and courage. Shared confession: fleece lies; fruit tells.

Reformed

Thus seals the criterion. The church’s safety is not cynicism but fruit-discernment under Christ’s Word.

The Shepherd who warns also keeps. Recognition by fruits is how His people stay on the narrow way among wolves.

Key contrast Both insist on fruit as the test of prophets. Arminians commonly stress grace-enabled, responsible discernment; Reformed readers commonly stress fruit as evidence of a nature remade—or exposed—under Christ’s sovereign care of the flock.

Historic quotes

Voices from both camps

Classic Arminian and Reformed comment on Matthew 7:15–20, in the writers’ own words.

Arminian Notable voices

“Beware of false prophets - Who in their preaching describe a broad way to heaven: it is their prophesying, their teaching the broad way, rather than their walking in it themselves, that is here chiefly spoken of. All those are false prophets, who teach any other way than that our Lord hath here marked out.”
John Wesley · Explanatory Notes upon the New Testament (on Matt 7:15–20)

Reformed Notable voices

“But beware of false prophets These words were intended to teach, that the Church would be exposed to various impositions, and that consequently many would be in danger of falling from the faith, if they were not carefully on their guard. We know what a strong propensity men have to falsehood, so that they not only have a natural desire to be deceived, but each individual appears to be ingenious in deceiving himself.”
