“If the heart be chiefly and directly fixed on God, and the soul engaged to glorify him, some degree of religious affection will be the effect and attendant of it. But to seek after affection directly and chiefly; to have the heart principally set upon that; is to place it in the room of God and his glory. If it be sought, that others may take notice of it, and admire us for our spirituality and forwardness in religion, it is then damnable pride; if for the sake of feeling the pleasure of being affected, it is then idolatry and self-gratification.”

“As it is with spiritual discoveries and affections given at first conversion, so it is in all subsequent illuminations and affections of that kind; they are all transforming. There is a like divine power and energy in them as in the first discoveries; they still reach the bottom of the heart, and affect and alter the very nature of the soul, in proportion to the degree in which they are given. And a transformation of nature is continued and carried on by them to the end of life, until it is brought to perfection in glory.”

“It does not answer the aim which God had in this institution, merely for men to have good commentaries and expositions on the Scripture, and other good books of divinity; because, although these may tend, as well as preaching, to give a good doctrinal or speculative understanding of the word of God, yet they have not an equal tendency to impress them on men's hearts and affections. God hath appointed a particular and lively application of his word, in the preaching of it, as a fit means to affect sinners with the importance of religion, their own misery, the necessity of a remedy, and the glory and sufficiency of a remedy provided; to stir up the pure minds of the saints, quicken their affections by often bringing the great things of religion in their remembrance, and setting them in their proper colours, though they know them, and have been fully instructed in them already. ”

“Seek not to grow in knowledge chiefly for the sake of applause, and to enable you to dispute with others; but seek it for the benefit of your souls.”

“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.”

“He that has doctrinal knowledge and speculation only, without affection, never is engaged in the business of religion.”

“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.”
