Waiting is essential to the spiritual life. But waiting as a disciple of Jesus is not an empty waiting. It is a waiting with a promise in our hearts that makes already present what we are waiting for. We wait during Advent for the birth of Jesus. We wait after Easter for the coming of the Spirit, and after the ascension of Jesus we wait for his coming again in glory. We are always waiting, but it is a waiting in the conviction that we have already seen God's footsteps.
Waiting for God is an active, alert - yes, joyful - waiting. As we wait we remember him for whom we are waiting, and as we remember him we create a community ready to welcome him when he comes.
