We read a prayer of Saint Columban on his Feastday; here is another prayer taken from his Instructions. An Advent Prayer indeed!
I beg you, my Jesus, fill my lamp with your light. By its light let me see the holiest of holy places, your own temple where you enter as the eternal High Priest of the eternal mysteries. Let me see you, watch you, desire you. Let me love you as I see you, and before you let my lamp always shine, always burn. AMEN Thought for the day: let my lamp always shine, always burn.
