One of the essential paradoxes of Advent: that while we wait for God, we are with God all along ,that while we need to be reassured of God’s arrival, or the arrival of our homecoming, we are already at home. While we wait, we have to trust, to have faith, but it is God’s grace that gives us that faith. As with all spiritual knowledge, two things are true, and equally true, at once. The mind can’t grasp paradox; it is the knowledge of the soul.
