Let our song praise your saving power;. You amid the raging foes. Were our sheltering tower. Furious they assailed us. But your arm availed us. And your word broke their sword. When our own strength failed us.. And your word broke their sword. When our own strength failed us.. Rock of Ages. Let our song praise your saving power;. You amid the raging foes. Were our sheltering tower. Furious they assailed us. But your arm availed us. And your word broke their sword. When our own strength failed us.. And your word broke their sword. When our own strength failed us.. Furious they assailed us. But your arm availed us. And your word broke their sword. When our own strength failed us.. And your word broke their sword. When our own strength failed us.
