Question: what is the difference between bread of life and ordinary bread?
Answer: The analogy between earthly and heavenly bread lies in the ability to sustain life; the difference lies in the inability of ordinary bread to sustain life in the presence of death (Blank 1981:361; Rusch 1978:388), while the Bread of Life sustains life eternally (Bultmann 1978:168; Keil 1997:111).
