Advent, like its cousin Lent, is a season for prayer and reformation of our hearts. Since it comes at winter time, fire is a fitting sign to help us celebrate Advent… If Christ is to come more fully into our lives this Christmas, if God is to become really incarnate for us, then fire will have to be present in our prayer. Our worship and devotion will have to stoke the kind of fire in our souls that can truly change our hearts. Ours is a great responsibility not to waste this Advent time.
Therefore, since we are receiving a kingdom that cannot be shaken, let us be thankful, and so worship God acceptably with reverence and awe, for our "God is a consuming fire."
