To me, the central message of Chanukah is "hope"--- that Hashem does not forget us; that no matter how dark it gets, the light will surely follow. And in fact, the light burns its brightest when it is darkest.
We are now enduring a period of deep darkness and it seems that in a matter of a few weeks, it could get darker still as we are sunk yet again into war with our neighbors. This war, by all accounts, will be an existential war. It is from this very darkness that the blazing light of the geulah shleimah will shine forth.
The heights we may attain are in direct proportion to the depths to which we have descended. From the heels of Mashiach may we merit by Hashem's great and abundant mercy to ascend to the level of Har Sinai...in this year and in these days.
May your joy in Chanukah neither waver nor fail and may it increase daily during these closing days with first a Chodesh tov and then Shabbat shalom!
