Query: A seeming contradiction.

Mr. Packer confuses me a bit. He seems to say 'seek Godly knowledge but don't dig too deep lest you become conceited'. All Christians need to 'know' for certain the entire gospel of Christ, how can anyone follow God unless they 'know' exactly what He's saying to us? The Corinthians had a 'wrong' knowledge of God and that's why Paul was admonishing them because they were following 'after men' (wrong knowledge) rather than Christ. The 'knowledge of God' is good and brings humility but the 'commandments of men'corrupts.
