The short answer to both these questions is, No!  Even the most intelligent man in the world is of no practical use to God.  As Isaiah 55: 8-9 tells us, “For My thoughts are not your thoughts, neither are your ways My ways, declares the Lord.  As the heavens are higher than the earth, so are My ways higher than your ways and My thoughts than your thoughts.”  For Luke 17:10 says, we are just unworthy servants totally dependent on the Lord for His benevolence and must trust that He is in control of any and all situations.
