Here is a saying ascribed to St. Jerome that everything a believer does is prayer and a proverb, “He who works faithfully prays twice.” This can be said because a believer fears and honors God in his work and remembers the commandment not to wrong anyone, or to try to steal, defraud, or cheat. Such thoughts and such faith undoubtedly transform his work into prayer and a sacrifice of praise.
– Martin Luther –
from A Simple Way to Pray
