“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.”

“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.”

“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.”

“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. ”

“Since holiness is the main thing that excites, draws, and governs all gracious affections, it is no wonder that all such affections tend to holiness. That which men love, they desire to have and to be united to, and possessed of. That beauty which men delight in, they desire to be adorned with. Those acts which men delight in, they necessarily incline to do.”

“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.”
