Scotland was the name in Europe above all others in which Calvinism became most firmly entrenched . . . [I]n no other land did Calvinism effect so tremendous a change in the national character and the national destiny.
Calvinism transformed the Scots. In the Middle Ages they were a notoriously rough and disorderly people who preferred to raid rather than to raise cattle . . . The Reformation changed all that. The Scots were to become a different people and the alteration was effected by the new kirk armed with the Book of Discipline.

I would venture the speculation that Reformed Christianity in China has been working a similar transformation since the 19th Century. Would that God again open the Middle East to the Gospel.
