“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 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.”

“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.”

“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. ”

“Friendship is a serious affection; the most sublime of all affections, because it is founded on principle, and cemented by time.”
