I don’t understand any of your comment.
Even though they were at har sinai they still did the egel and they still tested Hashem 10 times in the midbar and asked “hayesh Hashem bikirbeinu ” by the mei merivah.
The nesayon of avodah zara was extremely powerful in previous generatioons and very smart and great people fell in.
Truthfully every aveira that is done bemeizid (loshon hora or tayvos looking at what we shouldn’t. ..) is due to a lack of emunah because if you believed strongly enough you wouldn’t dare and would never want to do something that is against the will of Hashem. Emunah is the hardest challenge and it is the challenge of the dor before moshiach hence ig is our challenge. The idea of emunah is that it has to be real it has go be felt. If you technically believe there’s a Hashem but don’t feel duty bound to His word then what is the emunah worth?
We are supposed to yearn for moshiach now when Hashems presence is not yet obvious. Once Moshiach has arrived obviously Hashem will be obvious and there will be no more need to yearn for moshiach because he is already here! But right now in this generation there are many who don’t yearn and don’t believe moshiach will come. Its very scary but I heard people say things like eh he’s never coming chas veshalom or other crazy comments.
