How do we know that the traditions of men are problematic?

In Mark 7, Jesus confronts the Pharisees for adhering to their traditions at the expense of God's commandments. He highlights that these traditions can make God's word of none effect, emphasizing that true worship should come from a heart aligned with God's instructions. By prioritizing human traditions over divine commandments, the Pharisees exemplified a critical error, showcasing that external rituals can detract from sincere devotion. This serves as a warning for Christians today to evaluate their own practices against scripture to ensure that they align with God's will rather than mere human customs.
