Q: Why did Jesus say, “You worship God in vain”?

A: Jesus warned, “You worship God in vain,” because many people appeared to honor God outwardly but ignored His actual commands. In Matthew 15, the Pharisees criticized Jesus’ disciples for not following the tradition of the elders, yet they themselves broke God’s commandments to keep human rules.

“Then some Pharisees and teachers of the law came to Jesus from Jerusalem and asked, ‘Why do your disciples break the tradition of the elders? They don’t wash their hands before they eat!’ Jesus replied, ‘And why do you break the command of God for the sake of your tradition?’”

Matthew 15:1–3

Jesus exposed their hypocrisy by quoting Isaiah. Their worship was empty because it was based on human teachings, not God’s word.

“You hypocrites! Isaiah was right when he prophesied about you: ‘These people honor me with their lips, but their hearts are far from me. They worship me in vain; their teachings are merely human rules.’”

Matthew 15:7–9

Today, the same warning applies. f people set aside God’s commands and instead follow traditions created by men, their worship becomes meaningless—even if it looks sincere on the outside. True worship means obeying God’s teachings and keeping the commands He established for our salvation. The Bible shows that when we cling to human rules, we lose the wisdom and understanding God gives to those who follow His will.

True worship requires more that words or religious activities. It requires obeying God’s commands with a sincere heart. When we follow God’s commandments instead of man-made traditions, we can receive all the blessings He promises us. Jesus’ message in Matthew 15 asks us to examine our worship and return to God’s commands so we can serve Him sincerely, not in vain. This is why the Church of God emphasizes returning to the faith Jesus taught — keeping the New Covenant. To learn more about the New Covenant established by Christ, visit our Beliefs page.
