Tonight is the first day of Hanukkah. It is a festival for remembrance of an event that happened over 2100 years ago.
Hanukkah means “dedication.” It is the commemoration of a re-dedication of the Temple. At the time, the Jews were under foreign rule. They were able to reopen their temple. So they did. But when they did, there was only enough oil for one day. Now the oil takes a week to make. The recipe is in the Old Testament (for Christians). But the people wanted to celebrate, so they set the oil to burning.
Miraculously the one day’s worth of oil burned for eight days, until the next batch of oil was prepared.
Jesus celebrated this holiday as the Festival of Lights.
I would expect God would know if He did the miracle. I think it is wonderful that He celebrated it.
