International Standard Bible Encyclopedia [4]
un - bḗ - lēv´ẽr : This word follows closely the lines of "unbelief" (which see) in its relation to originals. Once only ( Acts 14:2 ) it represents the participle ἀπειθοῦντες , apeithoúntes , "disobeying (ones)." Elsewhere (nine cases) it represents ἄπιστος , ápistos , "faithless," "without faith." In six of these passages (all in 1 and 2 Corinthians) it denotes the unconverted pagan as distinguished from the convert. In the other passages ( Luke 12:46; Titus 1:15; Revelation 21:8 ) the reference is to the unbelief which comes of moral resistance to God.
