Sometimes spiritual truth is best communicated through the imagination …but the non-fiction imagination comes in many different forms, and one form is themetaphor. Jesus, we are told, is “the Lamb of God” (John 1:29), a metaphorical truth meaning at the same time Jesus is and is not a lamb. Metaphors lead us to embrace a thing (Christ crucified) in terms of some, but not all, of the characteristics of another thing (a lamb).
Desiring God put Doug Wilson on the line to talk about metaphor and meaning and to explain why metaphor is more than a garnish to sprinkle on prose, but finds itself deeply embedded in the process of Christian logic.
