How do we know false prophets from true believers?

Jesus warns of false prophets in Matthew 7, stating they appear as sheep but are inwardly ravenous wolves. The distinction between true and false prophets is made clear by their fruits—true believers exhibit good works that align with their faith in Christ. This principle applies not only to prophets but to all who claim to follow Christ, suggesting that good trees produce good fruit while corrupt trees cannot yield true goodness. Hence, the examination of one's life and deeds provides evidence of their true spiritual condition.
