What is advent?
The early Christians developed the “church’s year” as a way of telling, learning, and reliving the story of Jesus, which stands at the heart of our faith. As they did so, they came to understand that it wasn’t simply a matter of going round and round the same sequence and never getting anywhere.
Think of a bicycle wheel; it goes round and round, but it is moving forwards, not standing still. . . . So it is with the church’s year. We go round the circuit: Advent, Christmas, Epiphany, Lent, Holy Week and Good Friday, Easter, Pentecost. The traditional Western churches sum all this up on Trinity Sunday, as we learn more deeply who our glorious God really is.
. . . [But] we are not simply going round and round the same topics and never getting anywhere. We are signing on as part of God’s larger project, God’s forward purposes, his plans for the whole creation to be renewed, so that (as the prophets said) the earth will be full of the knowledge and glory of the Lord, as the waters cover the sea. . . . That is the Advent hope.
So the Church’s year overlaps with itself. In Advent, we think our way back to the ancient people of God, to the call of Abraham and his family as the start of God’s rescue operation for a world in ruins and a human race in chaos. We follow the story of Israel’s hope, a hope that refused to die no matter what terrible things happened; a hope that the first Christians believed had become human in the baby Jesus.
With that “first Advent,” it was clear that God’s rescue operation for humans and the world had been decisively begun but not yet completed. Jesus really did launch God’s kingdom “on earth as in heaven” in his public career, his death, and his resurrection. But it was clear, because of the sort of thing this kingdom was, that it would then need to make its way through the humble, self-giving service of Jesus’ followers, until the time when Jesus would return to finish the work, to put all things right, to banish evil and death forever, and bring heaven and earth completely together.
The “second Advent” then, overlaps with the first. We celebrate Jesus’ first coming, and use that sense of fulfilment to fuel our hope for his second coming and to strengthen us to work for signs of that kingdom in our own day. . . . That is one way of saying what it means to be a follower of Jesus.
