There is the fire of the pillar, which illuminates our path so that we may travel by day, and by night.
There is the violent, trembling fire of the mountain from which G-d descends from the Heavens to be heard by us.
And there is the fire through which G-d responds, and is identified as the one true G-d by us.
It is through fire, Rashi tells us, that the Law of G-d was written.
There is the perpetual fire,
Esh Tamid, eternally burning on its altar, inextinguishable. A fire which cleanses us of sin – both intentional and unintentional – and thus extinguishes our transgressions.
