This is one of my beloved songs. I first heard it in college thanks to a thoughtful English Literature prof. The juxtaposition of the hopeful words and the state of the singer moves me. . .to think past moments of salvation. While Jesus, by definition, cannot fail, his life force can only be represented in always flawed reality, especially humanity. Sometimes I remember that the homeless person singing this truth has been failed, not by the blood, but by the content.
