how ought we deal with tyranny?

When tyrants reign, let us first remember our faults, which are chastised by such scourges; and, therefore, humility will restrain our impatience. Besides, it is not in our power to remedy these evils, and all that remains for us is to implore the assistance of the Lord, in whose hand are the hearts of men and the revolutions of kingdoms.

John Calvin, Aphorism 98
