The candle we light for the second Sunday is Advent is known as the Bethlehem candle to highlight the journey to Bethlehem, towards possibility of peace through the birth of Jesus.  You might not feel particularly peaceful at this moment but today set aside some time to spend in silence.  Invite God into your time and sit still. If an intrusive thought comes through, acknowledge it and let it pass through without dwelling on it. You may wish to start with the breath prayer and then move into the silent time.
