His Master's Voice

Unsure hesitating he cracks, 
He smiles through closed eyes. 
Pressing on there lies a song, 
His heart now sings, 
The deeper chords rejoice, 
He's now his Master's voice. 

For sure there's a breaking of heart, 
In time his reward is to see, 
The Lord his King, 
The Creator brings 
The song of life his choice, 
He's now his Master's voice.
