I.e., so long as they remain blind to the truth in consequence of their unwillingness to acknowledge it - and this in accordance with the law of cause and effect which God has imposed on His creation (see surah {2}, note [7]).
Where there is sheer obstinacy and ridicule of faith, the result will be that such a sinner's heart will be hardened and his eyes will be sealed, so that he cannot even see the things visible to ordinary mortals. The sinner gathers impetus in his descent towards wrong.
Cf. ii. 15. God's grace is always ready to help human weakness or ignorance and to accept repentance and give forgiveness. But where the sinner is in actual rebellion, he will be given none, and it will be his own fault if he wanders about distractedly, without any certain hope or refuge.
