1. We'll build on the Rock, the living Rock, On Jesus, the Rock of Ages; So shall we abide the fearful shock, When loud the tempest rages. Refrain: We'll build on the Rock, We'll build on the Rock We'll build on the Rock, on the solid Rock, On Christ, the mighty Rock. 2. Some build on the sinking sands of life, On visions of earthly treasure; Some build on the waves of sin and strife, Of fame, and worldly pleasure. 3. O build on the Rock forever sure, The firm and the true foundation; Its hope is the hope which shall endure, The hope of our salvation.
