“Who will deny that true religion consists, in a great measure, in vigorous and lively actings of the inclination and will of the soul, or the fervent exercises of the heart? That religion which God requires, and will accept, does not consist in weak, dull, and lifeless, wishes, raising us but a little above a state of indifference. ”

“But yet it is evident that religion consists so much in affection, as that without holy affection there is no true religion; and no light in the understanding is good which does not produce holy affection in the heart: no habit or principle in the heart is good which has no such exercise; and no external fruit is good which does not proceed from such exercises.”

“Religion consists much in holy affection; but those exercises of affection which are most distinguishing of true religion are these practical exercises. Friendship between earthly friends consists much in affection; but those strong exercises of affection that actually carry them through fire and water for each other are the highest evidences of true friendship.”

“But it is doubtless true, and evident from [the] Scriptures, that the essence of all true religion lies in holy love; and that in this divine affection, and an habitual disposition to it, and that light which is the foundation of it, and those things which are the fruits of it, consists the whole of religion.”

“We should get into the way of appearing lively in religion, more by being lively in the service of God and our generation than by the liveliness and forwardness of our tongues, and making a business of proclaiming on the house tops with our mouths the holy and eminent acts and exercises of our own hearts. Christians that are intimate friends would talk together of their experiences and comforts in a manner better becoming Christian humility and modesty, and more to each other's profit: their tongues not running before, but rather going behind their hands and feet, after the prudent example of the blessed apostle, 2 Cor. xii. 6. Many occasions of spiritual pride would thus be cut off, and so a great door shut against the devil. A great many of the main stumbling-blocks against experimental and powerful religion would be removed, and religion would be declared and manifested in such a way that, instead of hardening spectators, and exceedingly promoting infidelity and atheism, it would, above all things, tend to convince men that there is a reality in religion, and greatly awaken them, and win them, by convincing their consciences of the importance and excellency of religion. Thus the light of professors would so shine before men, that others, seeing their good works, would glorify their Father which is in heaven.”

“Divines are generally agreed that sin radically and fundamentally consists in what is negative, or privative, having its root and foundation in a privation or want of holiness. And therefore undoubtedly, if it be so that sin does very much consist in hardness of heart, and so in the want of pious affections of heart, holiness does consist very much in those pious affections.”

“Take away all the moral beauty and sweetness in the Word, and the Bible is left wholly a dead letter, a dry, lifeless, tasteless thing. By this is seen the true foundation of our duty, the worthiness of God to be so esteemed, honoured, loved, submitted to, and served, as He requires of us, and the amiableness of the duties themselves that are required of us. And by this is seen the true evil of sin; for he who sees the beauty of holiness must necessarily see the hatefulness of sin, its contrary. By this men understand the true glory of heaven, which consists in the beauty and happiness that is in holiness. By this is seen the amiableness and happiness of both saints and angels. He that sees beauty of holiness, or true moral good, sees the greatest and most important thing in the world, which is the fulness of all things, without which all the world is empty, no better than nothing, yea, worse than nothing. Unless this is seen, nothing is seen that is worth the seeing; for there is no other true excellency or beauty. Unless this be understood, nothing is understood that is worthy of the exercise of the noble faculty of understanding. This is the beauty of the Godhead, and the divinity of Divinity (if I may so speak), the good of the infinite Fountain of good; without which, God Himself (if that were possible) would be an infinite evil; without which we ourselves had better never have been; and without which there had better have been no being.”
