What does Psalm 94:11 say about the thoughts of man?

Les explains that Psalm 94:11 says, “the Lord knoweth the thoughts of man,” and they are vanity. He emphasizes that God even knows our thoughts and everything we think. In the final analysis, man's thoughts will go up in a puff of smoke and amount to nothing. Les also notes that even though he is an adherent of Paul's epistles as the meat and potatoes for us today, that does not mean the rest of Scripture is canceled; it all fits together.
