Neville imagines his ruined friend able to repay him, and he does

Five years before this lecture, a close friend of Neville's fell into financial ruin -- 'his world of Caesar collapsed upon him' -- and in that state owed Neville money. Rather than ever raising the debt, Neville periodically imagined the friend able to pay him back. The week of this lecture, feeling his prayer answered, he pictured a specific scene of the friend calling and visiting to repay him in person; two days after doing so, the friend called, came to this lecture that night, and afterward paid what he owed.
