I.e., their longing for a "second chance" is not dictated by love of truth for its own sake but rather, by their dread of the evil consequences of their doings; and "faith is useless unless it is desired for its own sake" (Razi).
Their falsity was not due to want of knowledge, but to perversity and selfishness. In their heart was a disease (ii. 10): therefore neither their understanding, nor their ears, nor their eyes do their proper work. They twist what they see, hear, or are taught, and go deeper and deeper into the mire. The deceptions which they used to practise on other people will, before the Seat of Judgement, become clear in their own eyes.
