Miseries of a Life to the last degree Brutish, did from the visible wretchedness and inconveniences thereof, gladly obey such whom they believed were (as they told them they were) Divinely sent to teach then a happier way of living. And in the Vertues which these their first Lawgivers taught them, their Successors easily retain'd them; continuing still to maintain in them a perswasion of their Divine Extraction, and Authority. From the which it will be found that this instance of the _Peruvian_ Morality makes for the need of Revelation to inforce Natural Religion, and not against it. But how far Revelation is needful to assist Natural Light, will be the best seen in reflecting a little upon what we receive from each of these Guides that God has given us. And if it shall appear from thence that Natural Religion has need of Revelation to support it; and that the Revelation which we have by Jesus Christ is exquisitely adapted to the end of inforcing Natural Religion; this will both be the highest confirmation possible, that to inforce Natural Religion or Morality, was the design of Christianity; and will also shew that to the want of their being in earnest Christians, is to be attributed the immorality of such who, professing Christianity, live immoral Lives. The consequence from whence must be, That to reclaim a Vicious People, it should be consider'd, as the most effectual means of doing so, how to make Men really, and in earnest Christians. To see what light we receive from Nature to direct our Actions, and how far we are Naturally able to obey that Light; Men must be consider'd purely as in the state of Nature, _viz._ as having no extrinsick Law to direct them, but indu'd only with a faculty of comparing their distant Ideas by intermediate Ones, and Thence of deducing, or infering one thing from another; whereby our Knowledge immediately received from _Sense_, or _Reflection_, is inlarg'd to a view of Truths remote, or future, in an Application of which Faculty of the mind to a consideration of our own Existence and Nature, together with the beauty and order of the Universe, so far as it falls under our view, we may come to the knowledge of a _First Cause_; and that this must be an _Intelligent Being, Wise_ and _Powerful_, beyond what we are able to conceive. And as we delight in our selves, and receive pleasure from the objects which surround us, sufficient to indear to us the possession and injoyment of Life, we cannot from thence but infer, that this _Wise_ and _Powerful Being_ is also most _Good_, since he has made us out of nothing to give us a Being wherein we find such Happiness, as makes us very unwilling to part therewith.
