Lesson of Rav Lessin

The Gemorah Kiddushin (31a) says that when the nations heard the first dibros they said God is demanding his own honor.  When they heard the later dibros then they realized that even the first one's were true.  Why do we need to know what the goyim thought?  What lesson does it teach us?  Furthermore, what is the difference if God is defending his own honor, He is still dictating the law?  And how do the latter dibros change the interpretation of the first dibros?  Rav Lessin explains that the Gemorah isn't referring to the mistake of your average street goy; it is  mistake of great thinkers and philosophers.  They think that God is too great too be involved in the life of every individual.  He is busy with great things, lecovod atzmo, Godly business, but he isn't involved in my basic, daily life.  Then they heard the last dibros, Hashem at this time of great revelation is giving basic commandments about the most basic, human affairs.  This proved that indeed Hashem is involved in the human existence, He monitors and is involved in every event of human affairs.
