The blues artists....sang, giving voice to their hope for deliverance, their hope that Sunday's coming. The blues invites us not only to embrace the curse but also simultaneously to embrace the cross. To see the broken made whole, the lost found. We see the exile and the stranger make their way back home. "I was blind, but now I see," says the classic hymn. Not through some cheap happy ending, but in the identification and the defeat of all sorrow and sin in the Man of Sorrows on the cross, the most solemn minor key ever sounded in human history. In short, the blues helps us understand what theologians call redemption, all of the realities of life under the cross.
