I say man must fall upon this Gospel and be broken to pieces and in deep consciousness lie prostrate, like a man that is powerless, unable to move hand or foot. He must only lie motionless and cry: Almighty God, merciful Father, now help me! I cannot help myself! Christ, my lord, do help now, for with only my own effort all is lost!
