Do you remember the 60's song by Simon and Garfunkel song which had the line, "Where have you gone, Joe DiMaggio, a nation turns its lonely eyes to you. What's that you say, Mrs. Robinson? Joltin' Joe has left and gone away." Originally it was part of the soundtrack for the film The Graduate, the song "Mrs. Robinson" has became one of the 1960s' best-known, iconic ballads.

But in a 60 Minutes interview Paul Simon mentioned that some time after the song was released, he received a letter from Joe DiMaggio in which DiMaggio expressed his befuddlement at what in the world that song could mean. DiMaggio wrote, "What do you mean 'Where have I gone?' I haven't gone anywhere! I'm still around I'm selling Mr. Coffee." Then Mr. Simon smiled wryly at Mike Wallace and remarked, "Obviously Mr. DiMaggio is not accustomed to thinking of himself as a metaphor!"

But then, who is? Most, if not all, of us see ourselves as real people with literal, descriptive identities. For instance, I am a pastor, a husband, a father, a committee member, a volunteer, a son these are all straightforward descriptions of who I am in relation to the people around me in life. Like most people, I cannot readily conceive of myself as a symbol for something, as a kind of metaphor that represents something beyond myself.

Indeed, if someone came up to you at a party and said, "You are my shelter from the storms of life," well, you'd be taken aback. Then again, if you met someone who constantly spouted self-referential metaphors, you'd have to wonder about him or her. We expect people to denote themselves by saying things like, "I am a plumber" or "I'm a stay-at-home Dad." But our eyes would widen if someone said, "I am the oil that lubes my company's machine" or "I am the antibody that shields my family from the virus of secularism."

This is not a terribly typical mode of discourse. Yet Jesus, with some frequency, did refer to himself in a metaphorical mode, starting with John 6:35 when Jesus said, "I am the Bread of life."
