A LAMP is an excellent way to keep the light of something or someone you care deeply about alive in your thoughts and prayers
I often light a lamp to help me acknowlege the people suffering in the world so that I will constantly add prayers to address those who are victims. I light a lamp for those who have suffered or lost their lives in Iraq and other troubled spots.
Since I have been using them, I have vigiled with them, and set up a memorial to a lost friend.
When a lamp is used in this way, OLIVE OIL becomes quite sacred. http://thebiblelamp.blogspot.com/
