You’re probably familiar with the phrase, “You will know them by their fruit,” from Matthew 7. It’s often used to judge whether someone’s faith is real, with the idea that a true Christian must prove their salvation through visible results. Some go so far as to treat this as a command to doubt every profession of faith until evidence is shown.

But this passage isn’t meant to test believers. In its context, Jesus is warning about false teachers, not questioning the salvation of sincere followers. His focus is on protecting people from spiritual deception, not urging them to challenge each other’s faith.

Jesus is talking about false prophets, that is, those who appear genuine but teach lies. They will show signs of who they really are. Their actions, morals, and even their followers can reveal their true nature. These outward signs are what expose their falsehood.

Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves. You will know them by their fruits. Grapes are not gathered from thorn bushes, nor figs from thistles, are they?

Matthew 7:15–16
