To enlarge on every one of those instances, particularly mentioned in this answer, in which this sin is supposed to consist, would require a distinct treatise, and be inconsistent with our designed brevity in explaining the Ten Commandments. All that we shall therefore attempt at present, shall be to consider some instances, in which practical Atheism discovers itself, together with the aggravations of this sin; and then we shall enquire what judgment we are to pass concerning those who complain of atheistical and blasphemous thoughts; and consider whether this be a degree of that Atheism which we are speaking of; together with the causes of this sin, and the remedies against it.

I. The instances in which practical Atheism discovers itself. And,

1. They are chargeable with it who are grossly ignorant, and know nothing of God but the name, being utter strangers to those perfections whereby he makes himself known to the world, or who entertain carnal conceptions of him, as though he were altogether such an one as ourselves, Psal. l. 21.

2. When persons, though they know, in some measure, what God is, yet never seriously exercise their thoughts about him; which forgetfulness is a degree of Atheism, and will be severely punished by him, Psal. ix. 17. and l. 22.

3. When persons maintain corrupt doctrines, and dangerous heresies, subversive of the fundamental articles of faith, and contrary to the divine perfections. Of this kind are those that militate against his sovereignty and dominion over the wills, consciences and affections of man; when persons conclude that his counsels and determinations may be disannulled or defeated; or when we suppose that he changes, as we do; or when, under a pretence of advancing one perfection, we set aside the glory of another, when in order to magnify his mercy, we disregard his holiness or justice, and so presume of being happy without being holy; or when we give way to despairing thoughts, from the consideration of his vindictive justice, without improving the displays of his mercy, as set forth in the gospel.

4. When we repine and quarrel at his providence, and pretend to find fault with the dispensations thereof, or charge God foolishly, and go about to prescribe laws to him, who is the Governor of the world, and may do what he will with the work of his hands.

5. When we refuse to engage in those acts of religious worship which he has appointed, or to attend on his ordinances, in which we may hope for his presence and blessing.

6. When we behave ourselves, in the conduct of our lives, as though we were not accountable to him, and had no reason to be afraid of his judgments. Accordingly, when we set our affections on other things, and take them off from him, when we are guilty of wilful impenitency and unbelief, and are incorrigible under divine rebukes; when our hearts and lives are estranged from him, as though we desired not the knowledge of his ways; when we resist and grieve his Spirit, are discontented and impatient under his hand, or ascribe that to second causes, or think that those things come by chance which are under the direction of his providence. In these, and many other instances, persons are notoriously guilty of practical Atheism, which is forbidden in this Commandment.

II. We are now to consider the aggravations and dreadful consequences of this sin.

1. It is contrary to the light of nature, and the dictates of conscience, a disregarding those impressions which God has made of his glory on the souls of men. And in those who have been favoured with the revelation of the grace of God in the gospel, in which his perfections have been set forth to the utmost, it is a shutting our eyes against the light and casting contempt on that which should raise our admiration, and excite in us the highest esteem of him whom we practically disown and deny.
