A law is the revealed will of a sovereign, in which a debt of obedience is demanded, and a punishment threatened, in proportion to the nature of the offence, in case of disobedience. And here we must consider, that as a subject is bound to obey a law; so he cannot justly be deprived of that which he has a natural right to, but in case of disobedience; therefore obedience to a law gives him a right to impunity, but nothing more than this; whereas a covenant gives a person a right, upon his fulfilling the conditions thereof, to all those privileges, which are stipulated, or promised therein. This may be illustrated, by considering it as applied to human forms of government, in which it is supposed that every subject is possessed of some things, which he has a natural or political right to, which he cannot justly be deprived of, unless he forfeit them by violating the law, which, as a subject, he was obliged to obey; therefore, though his obedience give him a right to impunity, or to the undisturbed possession of his life and estate, yet this does not entitle him to any privilege, which he had no natural right to. A king is not obliged to advance a subject to great honours, because he has not forfeited his life and estate by rebellion: but in case he had promised him, as an act of favour, that he would confer such honours upon him, upon condition of his yielding obedience in some particular instances, then he would have a right to them, not as yielding obedience to a law, but as fulfilling the conditions of a covenant.
