Yesterday was the first Sunday of Advent. At my church, we lit the first Advent candle and sang our traditional Advent song that counts down the weeks toward Jesus' birth.
Advent and Lent are the two seasons on the liturgical calendar that our church regularly observes. A lot of churches ignore the calendar all together, but I think that's a mistake. Remembering Jesus' birth and passion are the bookends of his life. As disciples of Jesus, His life is ours. That's why I see value having regular seasons of worship to reflect on Jesus.
On the front of our bulletins this month, I've printed a quote by Dr. Wayne Grudem, taking from his systematic theology. It summarizes well what we celebrate about Jesus in this Advent season:
"Remaining what he was, he became what he was not."
