For generations, the people of the world walked in darkness, unable to find their way. They yearned for a king who would lead them. Could This Be the Day? is one of the most memorable moments from Joseph and Pamela Martin's cantata, Canticle of Joy, and is available here as a separate octavo. Orchestrated by Brant Adams and incorporating O Come, O Come. Emmanuel, this hauntingly beautiful Advent choral expresses the world's deep longing and emotional prayers of hope that the Messiah will come.
