For what reason could they not believe? Is it because they were rejected by their Maker before the world began? Is it about their being born guilty of Adam’s sin and thus incapable of responding willingly to God’s own appeals for reconciliation? Of course not! They are being temporarily blinded in their already calloused condition so as to accomplish redemption for the world. This is not about God rejecting most of humanity before the world began as the Calvinistic systematic reads into these texts.
