{Being in readiness} (en hetoim(9369) echontes). This very
idiom occurs in Polybius, Philo, etc. "Holding in readiness." In
 12:14  we have hetoim(9373) ech(935c) for the same idea (adverb
hetoim(9373)). {Disobedience} (parako(886e)). Rare word (Plato,
papyri) hearing amiss (aside), failing to hear, refusing to heed
(cf.  Mt 18:17  for same idea in parakou(935c)). In N.T. only here;
 Ro 5:19  Heb 2:2 . In contrast with hupako(885c) (obedience) rather
than the common apeithia ( Ro 11:30,32 ). {When your obedience
shall be fulfilled} (hotan pl(8872)(9374)h(8869) hum(936e) h(8820)hupako(885c)).
Indefinite temporal clause with hotan and first aorist passive
subjunctive. Paul expects that the whole church will become
obedient to Christ's will soon as came true.
