It has been said, “Prayer is the key which unlocks the door of God’s treasure house.” In the classic book, The Kneeling Christian, the author (unknown) prefaced the book saying, “It is not too much to say that all real growth in the spiritual life depends upon the practice of prayer.” Later he wrote,
The greatest thing we can do for God or for man is to pray. We can accomplish far more by our prayers than by our work. Prayer is omnipotent. It can do anything that God can do! When we pray God works. All fruitfulness in service is the outcome of prayer – of the worker’s prayers, or of those who are holding up holy hands on his behalf.
