Petra - Backslidin' Blues lyrics

Please tell me what makes me feel this way I've been down to the bottom and I don't want to stay Tell me what can I do To get back to You? I got the blues Those backslidin' blues I can see it, I've been on the wrong road And I'm too tired to carry such a heavy load Satan's marking me now I can't take it no more I got the blues Those backslidin' blues Have mercy, take me back once again I'll never be perfect and I sure haven't been I know that you will But you know that until I got the blues Those blackslidin' blues
