“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.”

“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.”

“For when God is said by these things to try men and prove them, to see what is in their hearts and whether they will keep His commandments or no, we are not to understand, that it is for His own information, or that He may obtain evidence Himself of their sincerity (for he needs no trials for His information); but chiefly for their conviction, and to exhibit evidence to their consciences...So when God tempted or tried Abraham with that difficult command of offering up his son, it was not for His satisfaction, whether he feared God or no, but for Abraham's own greater satisfaction and comfort, and the more clear manifestation of the favour of God to him.”

“He is wretched indeed, who goes up and down in the world, without a God to take care of him, to be his guide and protector, and to bless him in his affairs [. . .] That unconverted men are without God shows that they are liable to all manner of evil [. . .] liable to the power of the devil, to the power of all manner of temptation [. . .] to be deceived and seduced into erroneous opinions [. . .] to embrace damnable doctrines [. . .] to be given up of God to judicial hardness of heart [. . .] to commit all manner of sin, and even the unpardonable sin itself. They cannot be sure they shall not commit that sin. They are liable to build up a false hope of heaven, and so to go hoping to hell [. . .] to die senseless and stupid, as many have died [. . .] to die in such a case as Saul and Judas did, fearless of hell. They have no security from it. They are liable to all manner of mischief, since they are without God. They cannot tell what shall befall them, nor when they are secure from anything. They are not safe one moment. Ten thousand fatal mischiefs may befall them, that may make them miserable forever. They, who have God for their God, are safe from all such evils. It is not possible that they should befall them. God is their covenant God, and they have his faithful promise to be their refuge.”

“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. ”

“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.”

“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.”
