“But saints and angels behold that glory of God which consists in the beauty of His holiness; and it is this sight only that will melt and humble the hearts of men, wean them from the world, draw them to God, and effectually change them. A sight of the awful greatness of God may overpower men's strength, and be more than they can endure; but if the moral beauty of God be hid, the enmity of the heart will remain in its full strength. No love will be enkindled; the will, instead of being effectually gained, will remain inflexible. But the first glimpse of the moral and spiritual glory of God shining into the heart produces all these effects as it were with omnipotent power, which nothing can withstand.”

“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.”

“A truly Christian love, either to God or men, is a humble broken-hearted love. The desires of the saints, however earnest, are humble desires. Their hope is a humble hope; and their joy, even when it is unspeakable and full of glory, is a humble broken-hearted joy, and leaves the Christian more poor in spirit, and more like a little child, and more disposed to a universal lowliness of behaviour.”

“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.”

“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.”

“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. ”

“Unless men may come to a reasonable, solid persuasion and conviction of the truth of the gospel, by the internal evidences of it, . . . by a sight of its glory; it is impossible that those who are illiterate, and unacquainted with history, should have any thorough and effectual conviction of it at all. They may without this, see a great deal of probability of it; it may be reasonable for them to give much credit to what learned men and historians tell them. . . . But to have a conviction, so clear, and evident, and assuring, as to be sufficient to induce them, with boldness to sell all, confidently and fearlessly to run the venture of the loss of all things, and of enduring the most exquisite and long continued torments, and to trample the world under foot, and count all things but dung for Christ, the evidence they can have from history, cannot be sufficient.”
