Who can say what power a church could develop and exercise if it gave itself to the work of prayer day and night for God's power on His servants and His word, and for the glorifying of God in the salvation of souls? Most churches think their members are gathered into one simply to take care of and build up each other. They do not know that God rules the world by the prayers of His saints, that prayer is the power by which Satan is conquered, that by prayer the Church on earth has as its disposal the powers of the heavenly world. They do not remember that Jesus has, by His promise, consecrated every assembly in His Name to be a gate of heaven, where His Presence is to be felt, and His Power experienced in the Father fulfilling their desires.
