543 apeítheia(from 1 /A "not" and 3982 /peíthō, "persuaded") – properly, someone not persuaded, referring to their willful unbelief, i.e. the refusal to be convinced by God's voice. This is the core-meaning of the entire word-family: 543 (apeítheia), 544 (apeithéō), 545 (apeithḗs). All these cognates focus on man's decision to reject God's offers of faith, i.e. refusal to be persuaded in their heart concerning obeying His will (Word).
