The text for reflection is Revelation 3:20.
Christ is still knocking. It is not yet Christmas. But it is also not the great final Advent, the final coming of Christ. Through all the Advents of our life that we celebrate goes the longing for the final Advent, where it says, “Behold, I make all things new” (Rev. 21:5). Advent is a time of waiting, Our whole life, however, is Advent—that is, a time of waiting for the ultimate, for the time when there be a new heaven and a new earth, when all people are brothers and sisters and one rejoices in the words of the angels: “On earth, peace to those on whom God’s favor rests.” Learn to wait, because he has promised to come. “I stand at the door…” We however call to him: “Yes, come soon, Lord Jesus!” Amen.
—Dietrich Bonhoeffer, “The Coming of Jesus in Our Midst”
(I beg my readers not to complain that waiting sounds passive and that the promise sounds individualistic. This is Dietrich Bonhoeffer [no passive-ist he], and this text is far from an individualistic hope.)
