"No Government can expect to prosper which refuses to recognize religion, which deals with its subjects as if they had no souls, and cares not whether they serve God, or Baal, or no God at all. Such a Government will find, sooner or later, that its line of policy is suicidal, and damaging to its best interests. No doubt the kings of this world cannot make men Christians by laws and statutes. But they can encourage and support Christianity, and they will do so if they are wise. The kingdom where there is the most industry, temperance, truthfulness, and honesty, will always be the most prosperous of kingdoms. The king who wants to see these things abound among his subjects, should do all that lies in his power to help Christianity and to discourage irreligion."
