Lyrics:

This is my desire:
To honour You
Lord, with all my heart.
I worship You.
All I have within me,
I give You praise.
All that I adore
Is in You.

Refrain: Lord, I give You my heart.
I give You my soul.
I live for You alone.
Every breath that I take,
Every moment I'm awake,
Lord, have Your way in me.
