Black sky, black sky, evenin' rain
Oh why, did I have to cause you pain?
I lie here wondering if I'll ever learn to keep my head
There's somethin' inside keeps pushin' me over the edge

I've tried, I've tried to shake this rage
But once it starts, it's so hard to disengage
I can't bear bein' so cruel to the ones I love
But there's a stranger in my heart and he's out for blood
He's out for blood

The devil's inside, the devil's inside
The devil's inside my heart
The devil's inside, the devil's inside
The devil's inside my heart
Leading my mind astray
Twisting everything I say
How can I fight the devil inside my heart?

Oh lord, dear lord, mercy please
He starves my heart so ruthlessly
The blackest dragon is he that chokes my light
Got me askin' for more and more when I should be satisfied
Why can't I be satisfied?

The devil's inside, the devil's inside
The devil's inside my heart
The devil's inside, the devil's inside
The devil's inside my heart
Leading my mind astray
Twisting everything I say
How can I fight the devil inside my heart?

The darkest phantom is he that chokes my light
Got me askin' for more and more when I should be satisfied
