[the Devil]... stands waiting for them, like greedy hungry lions that see their prey, and expect to have it... - Jonathan Edwards

Thus there is a difference between having an opinion that God is holy and gracious, and having a sense of the loveliness and beauty of that holiness and grace. There is a difference between having a rational judgment that honey is sweet, and having a sense of its sweetness. A man may have the former, that knows not how honey tastes; but a man can’t have the latter unless he has an idea of the taste of honey in his mind. So there is a difference between believing that a person is beautiful, and having a sense of his beauty.

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.

Prayer is as natural an expression of faith as breathing is to life.
