“In Deo sola spec mea" is a conceptual title, meaning "My hope (is) in God alone." The title of the work does not directly appear in the piece.
Musically, the first phrase, "But it is good for me to adhere to my God, to put my hope in the Lord God," is re-worked in a variation of ways, similar to the various ways in which we might find ourselves placing our hopes in God through the trials and triumphs in life. The phrasing rises and falls, as our emotional states often do, finally culminating in a victorious declaration of praise for His goodness in times of trouble and defeat.
Culturally and poetically, the phrase "Daughter of Sion" was a metaphor for Israel and the loving, caring, patient relationship God has with His chosen people. To praise God in her gates would have been a great symbol of hope in the their God and His promises to them as a nation.
The last section is filled with the resolve to continue in hope.
