When Levin thought what he was and what he was living for, he could find no answer to the questions and was reduced to despair; but when he left off questioning himself about it, it seemed as though he knew both what he was and what he was living for, acting and living resolutely and without hesitation.
There is one death bed repentance recorded in the Bible (the thief on the cross), so that no one despair, but there is ONLY one, so that no one will presume.
Nothing is unimportant to a man plunged in despair. He is as credulous as a criminal sentenced to death who listens to a lunatic raving to him about how he can escape through the keyhole.
