Statesmen, my dear Sir, may plan and speculate for liberty, but it is religion and morality alone, which can establish the principles upon which freedom can securely stand. The only foundation of a free constitution is pure virtue; and if this cannot be inspired into our people in a greater measure than they have it now, they may change their rulers and the forms of government, but they will not obtain a lasting liberty. They will only exchange tyrants and tyrannies. You cannot, therefore, be more pleasantly or usefully employed than in the way of your profession, pulling down the strong-holds of Satan. This is not cant, but the real sentiment of my heart. Remember me with much respect to your worthy family and to all friends.
