“So that it must be only by the imagination that Satan has access to the soul, to tempt and delude it, or suggest anything to it. And this seems to be the reason why persons that are under the disease of melancholy are commonly so visibly and remarkably subject to the suggestions and temptations of Satan... Innumerable are the ways by which the mind may be led on to all kind of evil thoughts, by the exciting of external ideas in the imagination.”

“The deceitfulness of the heart of man appears in no one thing so much as this of spiritual pride and self-righteousness. The subtlety of Satan appears in its height, in his managing persons with respect to this sin. And perhaps one reason may be that here he has most experience; he knows the way of its coming in; he is acquainted with the secret springs of it: it was his own sin. Experience gives vast advantage in leading souls, either in good or evil.”

“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.”

“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.”

“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.”

“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.”

“And yet some people actually imagine that the revelation in God’s Word is not enough to meet our needs. They think that God from time to time carries on an actual conversation with them, chatting with them, satisfying their doubts, testifying to His love for them, promising them support and blessings. As a result, their emotions soar; they are full of bubbling joy that is mixed with self-confidence and a high opinion of themselves. The foundation for these feelings, however, does not lie within the Bible itself, but instead rests on the sudden creations of their imaginations. These people are clearly deluded. God’s Word is for all of us and each of us; He does not need to give particular messages to particular people.”
