It appears that in some parts of the world, prayers have legit market value. For example, a church in Russia is getting away with a $11,500 debt by promising to pray for the good health of the creditors instead.
The Nizhny Novgorod diocese of the Russian Orthodox Church owed 916,000 roubles to construction company Era for designing a heating system for one of their buildings. The church was only able to settle half the amount, and the company decided on taking legal action. But the owners of the company happen to be religious people, so the church was able to convince them to agree to a pre-trial settlement in which the loan would be written off and the church would pray for them in exchange.
