In tomorrow's first reading, King David laments that he lives in a palace while the Lord lives in a tent. Our first reading may seem unusual until you take a look at the selection of Saint Luke for the day. In this selection we have the story of the Annunciation. The angel Gabriel gives Mary the message that she will bear the Christ child in her womb.
While a tent housed the Ark in David's time, Mary is the Ark of the New Covenant: Christ tenting among his people by finding his first home in Mary's womb.
And set below is a video of John Collier speaking about his painting, The Annunciation.
