“In the soul where Christ savingly is, there He lives. He not only lives without it, so as violently to actuate it, but He lives in it, so that the soul also is alive. Grace in the soul is as much from Christ, as the light in a glass, held out in the sunbeams, is from the sun. But this represents the manner of the communication of grace to the soul only in part; because the glass remains as it was, the nature of it not being at all changed; it is as much without any lightsomeness in its nature as ever. But the soul of a saint receives light from the Sun of Righteousness, in such a manner that its nature is changed, and it becomes properly a luminous thing; not only does the sun shine in the saints, but they also become little suns, partaking of the nature of the Fountain of their light. In this respect, the manner of their derivation of light is like that of the lamps in the tabernacle, rather than that of a reflecting glass; which, though they were lit up by fire from heaven, yet thereby became themselves burning shining things.”

“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.”

“The soul of man, left to its own natural level, is a potentially lucid crystal left in darkness. It is perfect in its own nature, but it lacks something that it can only receive from outside and above itself. But when the light shines in it, it becomes in a manner transformed into light and seems to lose its nature in the splendor of a higher nature, the nature of the light that is in it.”

“But that is the nature of true grace and spiritual light, that it opens to a person's view the infinite reason there is that he should be holy in a high degree. And the more grace he has, and the more this is opened to view, the greater sense he has of the infinite excellency and glory of the divine Being, and of the infinite dignity of the person of Christ, and the boundless length and breadth and depth and height of the love of Christ to sinners. And as grace increases, the field opens more and more to a distant view, until the soul is swallowed up with the vastness of the object, and the person is astonished to think how much it becomes him to love this God and this glorious Redeemer that has so loved man, and how little he does love. And so the more he apprehends, the more the smallness of his grace and love appears strange and wonderful: and therefore he is more ready to think that others are beyond him.”

“Just as the sun shines on all the trees and flowers as if each were the only one on earth, so does God care for all souls in a special manner.”

“God is the highest good of the reasonable creature. The enjoyment of him is our proper; and is the only happiness with which our souls can be satisfied. To go to heaven, fully to enjoy God, is infinitely better than the most pleasant accommodations here. Better than fathers and mothers, husbands, wives, or children, or the company of any, or all earthly friends. These are but shadows; but the enjoyment of God is the substance. These are but scattered beams; but God is the sun. These are but streams; but God is the fountain. These are but drops, but God is the ocean.”

“People are like stained-glass windows. They sparkle and shine when the sun is out, but when the darkness sets in, their true beauty is revealed only if there is a light from within.”
