The questions relating to efficacious grace, controverted between us [Calvinists] and the Arminians, are two: 1. Whether the grace of God, in giving us saving virtue, be determining and decisive. 2. Whether saving virtue be decisively given by a supernatural and sovereign operation of the Spirit of God; or, whether it he only by such a divine influence or assistance, as is imparted in the course of common providence, either according to established laws of nature, or established laws of God’s universal providence towards mankind; i.e. either, 1. Assistance which is given in all natural actions, wherein men do merely exercise and improve the principles of nature and laws of nature, and come to such attainments as are connected with such exercises by the mere laws of nature. For there is an assistance in all such natural actions; because it is by a divine influence that the laws of nature are upheld; and a constant occurrence of divine power is necessary in order to our living, moving, or having a being. This we may call a natural assistance. Or, 2. That assistance, which though it be something besides the upholding of the laws of nature, (which take place in all affairs of life,) is yet, by a divine, universal constitution in this particular affair of religion, so connected with those voluntary exercises which result from this mere natural assistance, that by this constitution it indiscriminately extends to all mankind, and is certainly connected with such exercises and improvements, as those just mentioned, by a certain, established, known rule, as much as any of the laws of nature. This kind of assistance, though many Arminians call it a supernatural assistance, differs little or nothing from that natural assistance that is established by a law of nature. The law so established, is only a particular law of nature; as some of the laws of nature are more general, others more particular: but this establishment, which they suppose to be by divine promise, differs nothing at all from many other particular laws of nature, except only in this circumstance, of the established constitutions being revealed in the word of God, while others are left to be discovered only by experience.
The Calvinists suppose otherwise; they suppose that divine influence and operation, by which saving virtue is obtained, is entirely from, and above common assistance, or that which is given in a course of ordinary providence, according to universally established laws of nature. They suppose a principle of saving virtue is immediately imparted and implanted by that operation, which is sovereign and efficacious in this respect, that its effect proceeds not from any established laws of nature. I mention this as an entirely different question from the other, viz. Whether the grace of God, by which we obtain saving virtue, is determining or decisive. For that it may be, if it be given wholly in a course of nature, or by such an operation as is limited and regulated perfectly according to established, invariable laws. For none will dispute that many things are brought to pass by God in this manner, that are decisively ordered by him, and are brought to pass by his determining providence.
