_In this first American edition the original text remains unaltered, the notes which Dr. Ridgley had subjoined to his work are retained, and for the sake of distinction, printed in Italics. The other notes have been added by Dr. Wilson; and in every instance wherein they have been selected by him from others, they are accompanied by marks of quotation, and the name of the author or book from whence they were taken._ PREFACE. The influence which the different sentiments of men, in matters of religion, have, for the most part, on their temper and behaviour towards one another, affords very little ground to expect that any attempt to explain or defend the most important doctrines of Christianity, should not be treated with dislike and opposition by some, how much soever it may afford matter of conviction to others. This consideration would have put a stop to my pen, and thereby saved me a great deal of fatigue, in preparing and publishing the following sheets, had it not been over-balanced by what I cannot, at present, think any other than a sense of duty, in compliance with the call of providence. I heartily wish there were no occasion to vindicate some of the great doctrines of the gospel, which were more generally received in the last age, than at present, from misrepresentation, as though the method in which they had been explained led to licentiousness, and the doctrines themselves, especially those of election, particular redemption, efficacious grace, and some others, that depend upon them, were inconsistent with the moral perfections of the divine nature: these are now traduced by many, as though they were new and strange doctrines, not founded on scripture, nor to be maintained by any just methods of reasoning deduced from it, or as if the duties of practical religion could not be inculcated consistently therewith. If this insinuation were true, our preaching would be vain, our hope also vain, and we should be found false witnesses for God, and have no solid ground whereon to set our feet, which would be a most tremendous thought. And, if this be not sufficient to justify my present undertaking, I have nothing to allege of equal weight.
