Matthew 13:45-46 read as a price list. The kingdom of heaven is like a merchant in search of fine pearls who, finding one pearl of great value, went and sold all that he had and bought it - and Neville is precise about what all that he had means. You do not liquidate stocks and bonds or sell your house; nothing in the world of Caesar is wanted. What it costs is everything you now believe in as a power that controls your life. Authority. Numerology. Teacup leaves. Astrology. The drugs you take, the diet you keep - vegetarian or meat eater, smoker or non-smoker, drinker or non-drinker, whichever of them you think is the way to God. Nobody will buy these from you; you give them up as valueless, which is why there is no price attached. And the condition is absolute: you cannot hold back one little thing in reserve in case this does not work, because a reservation for a rainy day guarantees rain. The pearl itself he names without hedging - your own wonderful human imagination, which is Christ. So the transaction is not an exchange of one belief for another but the surrender of every competing power, and he closes it with Isaiah's paradox: come buy wine, buy milk, without money, without price.
