We hear much in our day of the rest of faith, but there is such a thing as the fight of faith in prayer as well as in effort. Those who would have us think that they have attained to some sublime height of faith and trust because they never know any agony of conflict or of prayer, have surely gotten beyond their Lord, and beyond the mightiest victors for God, both in effort and prayer, that the ages of Christian history have known. When we learn to come to God with an intensity of desire that wrings the soul, then shall we know a power in prayer that most of us do not know now.
R.A. Torrey
