Parshas Vayechi

[Ayala1]

In this week's shiur, Rav Reichman spoke about the Shem MiShmuel's idea that the sun represents constancy - the state of olam habah, where good is eternal and doesn't change. The moon on the other hand, represents change - growth and decline, both good and evil.
I wonder how this fits in with the idea that the Sefat Emet explains,  that in nature there is no chidush. Only above nature, in direct connection with Hashem is there real renewal, and constant chidush. In galus, chidush is hidden because Hashem acts with hester. It takes emunah – which is the ability to see Hashem even in galus – in order to get to the chidush. The moon is connected to emunah, since it shines at night, in times of darkness, and it’s the paradigm of chidush, and reminds us that chidush is always possible. It seems that the Sefat Emet takes a different aproach to the Shem MiShmuel, in saying that chidush is a positive thing that we must strive to attain through emunah.
