The depravity of nature appears, in that the general consequence of the state and tendency of man’s nature is a much greater degree of sin, than righteousness; not only with respect to value and demerit, but matter and quantity.

I have before shown, that there is a propensity in man’s nature to that sin, which in heinousness and ill desert immensely outweighs all the value and merit of any supposed good, that may be in him, or that he can do. I now proceed to say further, that such is man’s nature, in his present state, that it tends to this lamentable effect, that there should at all times, through the course of his life, be at least much more sin, than righteousness; not only as to weight and value, but as to matter and measure; more disagreement of heart and practice from the law of God, and from the law of nature and reason, than agreement and conformity. The law of God is the rule of right, as Dr. T. often calls it: It is the measure of virtue and sin: so much agreement as there is with this rule, so much is there of rectitude, righteousness, or true virtue, and no more; and so much disagreement as there is with this rule, so much sin is there. Having premised this, the following things may be here observed.

I. The degree of disagreement from this rule of right is to be determined, not only by the degree of distance from it in excess, but also in defect; or in other words, not only in positive transgression, or doing what is forbidden, but also in withholding what is required. The divine Lawgiver does as much prohibit the one as the other, and does as much charge the latter as a sinful breach of his law, exposing to his eternal wrath and curse, as the former. Thus at the day of judgment, as described Matt. xxv. The wicked are condemned as cursed, to everlasting fire, for their sin in defect and omission: I was an hungred, and ye gave me no meat, &c. And the case is thus, not only when the defect is in word or behaviour, but in the inward temper and exercise of the mind. 1 Cor. xvi. 22 . “If any man love not the Lord Jesus Christ, let him be Anathema Maranatha.” Dr. T. speaking of the sentence and punishment of the wicked, (Matt. xxv. 41, 46.) says, p. 159: “It was manifestly for want of benevolence, love, and compassion to their fellow-creatures, that they were condemned.” And elsewhere, as was observed before, he says, that the law of God extends to the latent principles of sin to forbid them, and to condemn to eternal destruction for them. And if so, it doubtless also extends to the inward principles of holiness, to require them, and in like manner to condemn for the want of them.

II. The sum of our duty to God, required in his law, is love; taking love in a large sense, for the true regard of our hearts to god, implying esteem, honour, benevolence, gratitude, complacence, &c. This is not only very plain by the Scripture, but it is evident in itself. The sum of what the law of God requires, is doubtless obedience to that law: no law can require more than that it be obeyed. But it is manifest, that obedience is nothing, any otherwise than as a testimony of the respect of our hearts to God: without the heart, man’s external acts are no more than the motions of the limbs of a wooden image; have no more of the nature of either sin or righteousness. It must therefore needs be, that love to God, the respect of the heart, must be the sum of the duty required in his law.

III. It therefore appears from the premises, that whosoever withholds more of that love or respect of heart from God, which his law requires, than he affords, has more sin than righteousness. Not only he that has less divine love, than passions and affections which are opposite; but also he that does not love God half so much as he ought, or has reason to do, has justly more wrong than right imputed to him, according to the law of God, and the law of reason; he has more irregularity than rectitude, with regard to the law of love. The sinful disrespect of his heart towards God, is greater than his respect to him.

But what considerate person is there, even among the more virtuous part of mankind, but would be ashamed to say, and profess before God or men, that he loves God half so much as he ought to do; or that he exercises one half of that esteem, honour, and gratitude towards God, which would be altogether becoming him; considering what God is, and what great manifestations he has made of his transcendent excellency and goodness, and what benefits he receives from him? And if few or none of the best of men can with reason and truth make even such a profession, how far from it must the generality of mankind be?

The chief and most fundamental of all the commands of the moral law, requires us to love the Lord our God with all our hearts, and with all our souls, with all our strength, and all our mind: that is, plainly, with all that is within us, or to the utmost capacity of our nature. God is in himself worthy of infinitely greater love, than any creature can exercise towards him; love equal to his perfections, which are infinite. God loves himself with no greater love than he is worthy of, when he loves himself infinitely; but we can give God no more than we have. Therefore, if we give him so much, if we love him to the utmost extent of the faculties of our nature, we are excused. But when what is proposed, is only that we should love him as much as our capacity will allow, all excuse of want of capacity ceases, and obligation takes hold of us; and we are doubtless obliged to love God to the utmost of what is possible for us, with such faculties, and such opportunities and advantages to know God, as we have. And it is evidently implied in this great commandment of the law, that our love to God should be so great, as to have the most absolute possession of all the soul, and the perfect government of all the principles and springs of action that are in our nature.
