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.
Jonathan EdwardsIf there be ground for you to trust in your own righteousness, then, all that Christ did to purchase salvation, and all that God did to prepare the way for it is in vain.
Jonathan EdwardsTrue virtue never appears so lovely as when it is most oppressed; and the divine excellency of real Christianity is never exhibited with such advantage as when under the greatest trials; then it is that true faith appears much more precious than gold, and upon this account is "found to praise and honour and glory.
