There are walls made by man built by frail and human hands That an enemy can scale and get to you. But there is one protecting me from my greatest enemy It's a wall that Satan can't break through. Sometimes a wall of grace sometimes a wall of faith Other times it's sweet mercy that I need. But the one for which I long it makes all the others strong. I need a wall of prayer surrounding me. II Oh my brother when I'm weak would you stand instead for me And pray a fortress 'round me strong that can't be moved. And I promise you today when I bow my knees to pray I'll do my best to build a wall of prayer for you. Ending Sweet hour of prayer sweet hour of prayer That calls me from a world of care. But the one for which I long it makes all the others strong. I need a wall of prayer surrounding me. I need a wall of prayer surrounding me.
