Lyrics:

Purify my heart
Let me be as gold and precious silver
Purify my heart
Let me be as gold, pure gold

Refiner's fire
My heart's one desire
Is to be holy
Set apart for You, Lord
I choose to be holy
Set apart for You, my Master
Ready to do Your will

Purify my heart
Cleanse me from within
And make me holy
Purify my heart
Cleanse me from my sin
Deep within
