As we look around and see the Menorahs in every window, we feel proud to be Jews and we give light to the world.
In the ancient world, and even up to the 1800's it was very difficult to light fire. Matches were not perfected, and the search for the proper materials to light and keep fire was very important. If your fire went out in the oven, then either you had to get fire from someone else, or use the special stones, strike them together, and let the spark fall on paper or other kindling. This often took a lot of time, and you had to be very practiced in this skill. Not everyone could do this.
So, in light of this, the fact that we light candles takes on new significance. Yes, it was difficult to light fire and to spread light.
Go out and Spread the light of the Torah!
