A popular tradition at Christmas time is for families to attend a Christmas Eve candlelight service together. If you have not attended one of these, envision sitting in a dimly lit room full of people. Each individual has their own candle, and once the first is aflame—usually led by the pastor—people begin spreading the flame from one candle wick to the next until all candles are lit. Whether there are just a handful or hundreds in the room, it does not take long before the once-dark area is beautifully aglow.
