This window depicts Jerusalem 'descending' from the Sky with the throne of a Lamb of God. The Lamb is a true light that enlightens the Holy City. This is a picture of a new, reborn world. "The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp." (Revelation 21,23) "Then I saw ?a new heaven and a new earth /.../ I saw the Holy City, the new Jerusalem, coming down out of heaven from God /.../ ?Look! God?s dwelling place is now among the people, and he will dwell with them." (Revelation 21,1-3)
