The Greek adjective aparaskeuastos means unprepared, unready, or lacking preparation. Appearing only once in the New Testament (2 Corinthians 9:4), it is used by Paul in a practical context about the Corinthians' readiness to fulfill their promised financial gift — but the word resonates far beyond its immediate setting.
Paul uses aparaskeuastos in 2 Corinthians 9:4, warning that if Macedonian believers arrive with him and find the Corinthian gift unready, both Paul and the Corinthians would be embarrassed. The immediate context is the collection for Jerusalem's poor believers — a project Paul invested enormous pastoral energy into as a symbol of Gentile-Jewish unity in the body of Christ. But 'unpreparedness' is one of the most consistently warned-against conditions in Jesus's own teaching. The foolish virgins were unprepared when the bridegroom came (Matthew 25:1–13). The man without a wedding garment was unprepared (Matthew 22:11–12). The servant found doing wrong when his master returned was unprepared (Matthew 24:44–50). The thread connecting them: the return of Christ demands active, sustained readiness. Aparaskeuastos is the spiritual condition Jesus most warns against — not gross sin, but the slow drift into unreadiness through delay, distraction, and assumption that there is always more time.
