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
