In that sense day by day I am enriched by the metaphors for knowing God . But delighting in the metaphors of the love of God gives me the assurance that I am loved eternally and welcome just as I am to the joy of heaven. But I don't have to say that those who don't know what a metaphor is, or ever think in those terms, or are plagued with wrong metaphors, are less loved and close to God than I am. An error cannot shine dazzlingly, but the metaphor suggests the error is very obvious. Some would argue that all adjectives, even the most scientific sounding ones were originally metaphors.

Thomas Stephen Szasz said that two things are needed to create a metaphor. Douglas Berggren used the idea of metaphorical tension. It is when the metaphorical tension is lost, and people take the metaphors literally, that misunderstanding occurs. He also pointed out that metaphors at first surprise and shock us.
