Augustine was constantly and painfully aware of encroaching darkness, in himself as well as in others: For there is still only a little light in men, and they must walk, yes, they must walk, that the darkness overtake them not (10.23). My father shared Augustine’s anxiety about wrong decisions. Despite each man’s confidence that (they) knew God’s will, they both acknowledged a “trembling” fear of wrong judgments. Perhaps this fear informed the regret and repentance they felt when close to death.
