Iron sharpens iron, deep cries to deep
The roar of the lion rouses from sleep
All who would heed the call of their election
He'll baptize them with fire
And work His ruthless perfection
Is it any wonder, is it any guess
How He will respond to the one who answers yes, yes
I will yield to Your love and Your correction
In mercy severe, He will work His ruthless perfection
As we behold Him, we will be like Him
Changed from glory into glory into glory again
As we behold Him, we will be like Him
Changed from glory into glory into glory again
Let's call on His kindness and fall on our face
Surrender the flesh to His judgment and grace
Comes the cross so comes the resurrection
Let us be made new by a work of ruthless perfection
All who would heed the call of their election
He will baptize them with fire
And work His ruthless perfection
Baptize them with fire
Baptize them with fire
Work His ruthless perfection
Ruthless perfection...
