All of the ground is sinking sand A doubting maze of desert land Where darkness rules the heart of man Til' the sun shines light on him Lord of all, Show you're strong On our knees we fall Chorus: Be a cornerstone Be a cornerstone Be a rock, higher than I Be my fortress wall Be a foundation for all, My cornerstone The building's swaying in the wind The towers crumble down again This certainly will be the end Of them not built on him Lord of all Show your strong On our knees we fall (Chorus) You You are the builder of my heart You Held me together from the start (Chorus)
