Last Supper 2

Similes are comparisons using "like" or "as." Jesus said, "The kingdom of God is LIKE a grain of mustard seed." Metaphors are comparisons made more directly and forcefully: "I AM the bread of life." Jesus used both similes and metaphors extensively, but when referring to himself, as in the "I AM's," he uses only metaphors.

Does it make a difference that Jesus said, "I AM the bread of life" rather than "I am LIKE bread that gives you life"?
