Original Word: ἀπιστέω
Part of Speech: Verb
Transliteration: apisteó
Phonetic Spelling: (ap-is-teh'-o)
Definition: to disbelieve, be faithless
Usage: I am unfaithful, disbelieve, refuse belief, prove false.

Cognate: 569 apistéō (from 571 /ápistos, "unfaithful," without faith, i.e. negating 4103 /pistós, "faithful") – properly, refusing to be persuaded by God ("betray His trust," J. Thayer).

569 /apistéō ("not willing to be persuaded") means more than "disbelieve" ("not believing") because it indicates "refusing to be faithful" (honor a trust or revelation from the Lord). See 571 (apistos).

569/apisteō ("refuse to be persuaded") is sin committed by believers (Mk 16:11; Lk 24:11,41) and unbelievers (Ac 28:24; Ro 3:3; 1 Pet 2:7). 569 (apistéō) reveals a person is unconvinced when they should be persuaded by what the Lord has done (offered).
