Philemon 1:11
Formerly he was useless to you, but now he is indeed useful both to me and to you — the name Onesimus (onēsimos — useful) creates wordplay: once unfruitful (achrēstos — useless), now profitable (euchrēstos — useful). The reversal is complete and multivalent: useful to Paul (providing service during imprisonment), useful to Philemon (redeemed slave now reliable), and useful to God (converted to Christ). The transformation of a wasted human into useful instrument exemplifies the gospel's redemptive power.
