The Bat Ayin (the Avritcher Rebbe) writes that the purpose of Chanukah is to fix the תוהו (the nothingness before creation) with light, similar to the אור of the first day of creation that countered the תוהו (the light that is hidden for tzaddikim for עולם הבא).
In the Torah, Avraham represents the idea of Chanukah.
