Quote from : True Christianity Book

Nay, we sometimes proceed so far as to trust in ourselves, and depend on our own power, strength, and abilities. Then it is that God in mere mercy interposes, and breaks us in pieces; humbles, and confounds us, and so empties us of ourselves, that we may be filled with all the fullness of God. Which we cannot be, without being first emptied of that arrogance and self-conceit which stand in perfect opposition to the grace of God. Hence it appears that hope is a MILITANT VIRTUE, fighting against all that confidence in ourselves; all that self-exaltation upon the score of our own gifts, merits, righteousness, prosperity, honours, and riches, in which the natural man reposes all his confidence. The business of hope is to oppose and conquer all these delusions of the devil, and to seek its rest in the sanctuary of God.
