In the ancient world there wasn't electricity like today, in fact the inside of a home was about as dim as a 40-watt light bulb. In the earliest of times lamps were stone bowls filled with animal fat. They would float a wick of twisted plant fibers. Later the bowls were made of pottery filled with olive oil. Most homes would contain several oil lamps because olive oil was in abundance and therefore not expensive. There was also an oven that provided a little bit of light, but the oil lamps were the main source of light in every home. Ancient lamps were oval shaped, and flat on top. They actually had small bowls on one end, with the other end pinched real tight which formed a groove to hold the cotton or flax wick. One end of the wick would even float in the olive oil. Some of the lamps had a lid over the bowl. They were usually made of clay, but the more expensive lamps were made of bronze and sometimes even of gold. Some of these were very beautiful and would contain very elaborate decorations, and many Roman lamps had images of their gods.
"Your word is a lamp to my feet And a light to my path."
"Or what woman, having ten silver coins, if she loses one coin, does not light a lamp, sweep the house, and search carefully until she finds it? And when she has found it, she calls her friends and neighbors together, saying, 'Rejoice with me, for I have found the piece which I lost!' Likewise, I say to you, there is joy in the presence of the angels of God over one sinner who repents."�
"Then Jesus spoke to them again, saying, "I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life."
