You will know them by what they do

A word for the week

You have met someone who said all the right things and something in you did not trust them, and later you found out you were right. And you have met someone who made no grand claims at all but whose life, when you looked at it, was full of quiet good. That gap, between what people say about themselves and what they actually do, is exactly what Jesus is teaching us to read in this passage, and it is the most important skill a watching people can have.

Beware of false prophets, he says, who come to you in sheep's clothing but inwardly are ravening wolves. That is the danger: the wolf that has learned to look like a sheep, the false thing dressed convincingly as the true. And how do you tell them apart, when the costume is good? Jesus gives the test in a single line, and it is the line our whole way of watching rests on. You will know them, he says, by their fruits, by which he means the one thing a costume cannot fake: what they actually do. Do people gather grapes from thornbushes, he asks, or figs from thistles? No. Sooner or later what a thing really is shows up in what it produces. The wolf, however woolly its disguise, eventually acts like a wolf. The good tree, whatever it claims or does not claim, quietly grows good things.

So the test is not what someone says, not how holy they sound, not how many impressive works they can point to. It is what their life actually yields: whether there is real love in it, real mercy, real humility, real care for the least. And Jesus drives it home with a warning that should sober anyone who trades in religious language. Not everyone who says to me, Lord, Lord, will enter the kingdom, he says, but the one who does the will of my Father. On the last day many will say, Lord, did we not prophesy in your name, cast out demons, do mighty works in your name? And he will say, I never knew you. Think about that. People doing spectacular religious things, using all the right words, even performing wonders, and it counts for nothing, because the words and the wonders were not backed by a life that actually did the will of God. Saying Lord is easy. Doing love is the test.

This is the plainest tool Jesus ever handed us for telling the true from the false, and it cuts against everything that dazzles. We are forever tempted to judge by the impressive: the powerful voice, the confident claim, the miraculous-seeming feat. Jesus says no; look past all of it to the deeds. What does this person, this teacher, this movement actually do? Does it bless the least or trample them? Does it produce mercy or cruelty, humility or pride? That, not the packaging, is what reveals what a thing truly is.

And notice how within reach this makes discernment. You do not need to be a scholar to apply it. A child can see whether someone is kind. You test by what they do, and their doings, over time, tell the truth their words may hide. Say it plainly to yourself and carry it everywhere: you will know them by what they do. It is the one test that no disguise, however good, can pass for long.
