In answering prayers, God normally relies on human agents. On a visit to Holland I heard the story of strict Dutch Calvinist farmers who, during the devastating floods of the 1950s, climbed onto the roofs of their barns but refused to be rescued. “God’s will be done,” they said.
they are illustrating belief in fatalism, not divine sovereignty (and how blurry the lines get between the two with hardline Calvinists).
