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.
