I. He will shew in what the principles of nature were, as they were God's creation; and how contrary to these principles, the world have walked, acted, and done. The principles of nature are concluded under three general heads.

1. That man by his own natural reason and judgment may gather, that there is a God, a Deity, a chief, or first, or principal Being, who is over all, and supreme above all. This instinct, I say, man merely as he is a rational creature findeth in himself; and hence it is, that all heathens that mind their own natural reason, do conclude, that we are his offspring; that is, His creation and workmanship. That He made heaven and earth, and hath made of one blood, all nations of men; that "in him we live, and move, and have our being;" &c. (Acts 17:24-29).

It appears further, that man by his own nature, doth know that there is such a God.

(1.) By his being able to judge by nature, that there is such a thing as sin; as Christ saith, "Why even of yourselves judge ye not what is right?" (Luke 12:57). As if he had said, You are degenerated even from the principles of nature, and right reason; as Paul saith in another place, "Doth not even nature itself teach you?" (1 Cor 11:14). Now he that can judge, that there is such a thing as sin, it must of necessity be, that he understandeth that there is a God, to whom sin is opposite; for if there be no God, there is no sin against him; and he that knows not the one, knows not the other.

(2.) It is evident further, that man by nature knows that there is a God, by those fits of fear, and dread that are often begotten in themselves, even in every man that breatheth in this world; for they are by their own consciences, and thoughts, convicted and reproved, judged and condemned, though they know neither Moses nor Christ—For the Gentiles which have not the law, these are a law to themselves, and shew the work of the law written in their hearts (Rom 2:14,15)—that is, by this very thing, they hold forth to all men, that God created them in that state and quality, that they might in and by their own nature, judge and know that there is a God. And it further sheweth itself, saith he, by those workings of heart, convictions of conscience, and accusations, that every thought maketh within them, together with the fear that is begotten in them, when they transgress, or do those things that are irrational, or contrary to what they see they shall do. I might add further, that the natural proneness that is in all men to devotion and religion, that is, of one kind or another, doth clearly tell us, that they by the book of nature, which book is themselves, do read that there is one great and eternal God.

2. The second principle of nature is, that this God should by man be sought after, that they might enjoy communion with him for ever. As I said before, the light of nature sheweth man, that there is a great God, even God that made the world; and the end of its shewing him this is, that "they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us" (Acts 17:27).

3. This light of nature teacheth, that men between themselves, should do that which is just and equal. As Moses said, and that long before the law was given, "Sirs, ye are brethren, why do ye wrong one another?" (Acts 7:26; Exo 2:13). as who should say, You are of equal creation, you are the same flesh; you both judge, that it is not equally done of any, to do you wrong, and therefore ought to judge by the same reason, that ye ought not to wrong one another.

Now against every one of these three principles, hath every man in the whole world transgressed; as Paul saith, "For both Jews and Gentiles—are all under sin" (Rom 3:9). For as touching the first, (1.) who is he that hath honoured, reverenced, worshipped, and adored the living God, to the height, both of what they saw in him, and also according to the goodness and mercy they have as men received from him? All have served and worshipped the creature more than the Creator, who is blessed for ever (Rom 1:25), and so have walked contrary to, and have sinned against, this bond of nature, in this first principle of it.

(2.) Men, instead of minding their own future happiness, as nature teacheth, they have, through their giving way to sin and Satan, minded nothing less; for though reason teacheth all men to love that which is good and profitable, yet they, contrary to this, have loved that which is hurtful and destructive. Yea, though sense teacheth to avoid the danger that is manifest; yet man, contrary to reason and sense both, even all men, have both against light and feeling, rejected their own happiness; as Paul saith, "Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them" (Rom 1:31).

(3.) Man, instead of doing equity, and as he would be done by, which nature itself teacheth: he hath given up himself to vile affections, being filled, by refusing the dictates of nature, "with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, without understanding, covenant-breakers, without natural affection, implacable, unmerciful" (Rom 1:29-31).
