How do we know Jesus' condemnation of religion is true?

In Mark 11, Jesus doesn't just verbally condemn the corrupt practices He sees; He acts decisively by overturning tables and driving out merchants from the temple. This act illustrates His authority as the head of the Church, calling out the empty rituals that had replaced genuine worship. Furthermore, He curses the unfruitful fig tree as a sign of God's judgment on false religion, demonstrating that it is not enough to merely appear religious outwardly while being spiritually dead. The drying up of the fig tree symbolizes the fate of all those who engage in hollow religious practices that bear no real fruit.
