The difference between worshiping Jesus and worshiping a generic world-spirit really does matter.
God is always working, but he often works in the silence.
The incarnation is the most important thing that ever happened. God is fully present to us through Jesus.
We huddle together in prayer, against the dark and the cold, waiting for Jesus to come.
The coming of Jesus is the central point of history. It is the center of our calendars, and should also be the center of our lives.
