This leads us to consider, II. The change that is wrought in this effectual calling, together with the grounds we have to conclude, that it is a supernatural work, or, as it is styled in this answer, the work of God’s almighty power and grace. Those whom we more especially oppose in this head of argument, are the Pelagians, and others; who, though in some things they seem to recede from them, yet cannot support their cause without giving into their scheme, when treating on the subjects of free-will, nature and grace: these all allow that there is a change made in conversion or effectual calling; but they suppose that it is a change in man’s natural temper and disposition, rather than what arises from a supernatural principle, which, according to them, consists in overcoming those habits of sin, which we have contracted, and acquiring habits of virtue, a ceasing to do evil, and learning to do well; and that it is in their own power supposing the concurrence of God as a God of nature, or at least, some superadded assistances, from the external dispensations of providence, which have an influence on the minds of men, to produce this change; by this means they think that grace is first attained, and we disposed to comply with the external call of the gospel, whereby it is rendered effectual. They sometimes indeed, use the word conversion, and speak of the power and grace of God herein; and that they may not seem to detract from the glory thereof, they profess themselves to adore and magnify God as the author of this work; but all this amounts to no more than nature acting under the influence of common providence. Something, indeed, they ascribe to God; but much less than what we think the scripture does. That which they ascribe to him therein, is, 1. That he has made man an intelligent creature, having a power capable of choosing whatever seems advantageous, or refusing what appears to be destructive to him; and in order hereunto, he is able to discern, what is his duty and interest; and when the will duly attends to these dictates of the understanding, it has a power inclining it to be influenced thereby, and embrace whatever overtures are made conducive to his future happiness. 2. Whereas the understanding and reasoning powers and faculties, are oftentimes impaired and hindered, in their method of acting, by some accidental inconveniences of nature, such as the temperament of the body, or those diseases which it is sometimes liable to, which affect the mind; these God, by his powerful providence, removes, or fences against, that the work may go on successfully.
