“From love arises hatred of those things which are contrary to what we love, or which oppose and thwart us in those things that we delight in.”

“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.”

“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.”

“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.”

“When God is here spoken of as hardening some of the children of men, it is not to be understood that God by any positive efficiency hardens any man's heart. There is no positive act in God, as though he put forth any power to harden the heart. To suppose any such thing would be to make God the immediate author of sin. God is said to harden men in two ways: by withholding the powerful influences of his Spirit, without which their hearts will remain hardened, and grow harder and harder; in this sense he hardens them, as he leaves them to hardness. And again, by ordering those things in his providence which, through the abuse of their corruption, become the occasion of their hardening. Thus God sends his word and ordinances to men which, by their abuse, prove an occasion of their hardening.”

“As God delights in his own beauty, he must necessarily delight in the creature's holiness which is a conformity to and participation of it, as truly as [the] brightness of a jewel, held in the sun's beams, is a participation or derivation of the sun's brightness, though immensely less in degree.”

“Men have a great deal of pleasure in human knowledge, in studies of natural things; but this is nothing to that joy which arises from divine light shining into the soul. This spiritual light is the dawning of the light of glory in the heart. There is nothing so powerful as this to support persons in affliction, and to give the mind peace and brightness in this stormy and dark world. This knowledge will wean from the world, and raise the inclination to heavenly things. It will turn the heart to God as the fountain of good, and to choose him for the only portion. This light, and this only, will bring the soul to a saving close with Christ. It conforms the heart to the gospel, mortifies its enmity and opposition against the scheme of salvation therein revealed: it causes the heart to embrace the joyful tidings, and entirely to adhere to, and acquiesce in the revelation of Christ as our Savior.”
