What does the Bible teach about hypocrites in religion?

Throughout Scripture, Jesus often addresses hypocritical behavior, particularly among religious leaders such as the Pharisees and Sadducees. He described them as actors who outwardly display compliance with God's law but internally are far from Him (Mark 12:15). Genuine faith involves a sincere relationship with God that goes beyond mere external actions. The New Testament calls believers to examine themselves to ensure their faith is genuine and true, emphasizing the need for a heart aligned with God's truths rather than mere lip service or societal favor.
