Do you know what you worship? While it may sound strange, it’s possible to offer vain worship towards that which we don’t even know. In John 4, Jesus met and spoke with a woman of Samaria. When she thought Jesus was a prophet, she asked the Lord about worship. See, the Samaritans worshipped at Mt. Gerazim, while Jews worshipped in Jerusalem. Jesus answered, “You worship what you do not know; we worship what we know, for salvation is from the Jews.”
I’m sure there were many well-intentioned Samaritans. But they rejected the Law of Moses and didn’t worship God as prescribed in the Law. Thus, Jesus said they didn’t even know what they worshipped, meaning they weren’t truly worshipping God. Do we make the same mistake? Perhaps we are well-intentioned and devout, but if we worship and live contrary to God’s Word, then we are not genuinely worshipping God and are guilty of worshipping that which we do not know.
