What warning does Jesus give about religious hypocrisy?

In His teachings, Jesus cautions against religious leaders, like the scribes, who exhibit hypocrisy through outward displays of piety while lacking genuine faith. They pursued recognition and prestige rather than true worship and service to God. This concern echoes the teachings found in John 12:42-43, where those who believed in Christ refrained from confessing Him due to fear of man. Such hypocrisy not only distances them from true faith but also leads to greater judgment. True religion, as defined by Christ, should produce a heart of mercy and humility that reflects the character of God.
