Throughout his letters, Paul uses several terms and images that originate from the world of ancient economics. Some of these terms are used metaphorically to describe God’s own attitudes and actions. The term ἀρραβών (‘earnest money, advance payment, bargain money’) may exemplify the use of a business term in the papyri in comparison with its use in Paul’s letters (in 2 Cor. 1.22 and 5.5; cf. Eph 1.14). In Paul’s image, God is depicted as a purchaser who offers ‘us’ his salvation for free and guarantees to complete it in the end. In using the term ἀρραβών, Paul emphasizes God’s reliability and unlimited trustworthiness within an insecure world.
