Prayer

[Beck]

"God has of his own motion placed himself under the law of prayer, and has obligated himself to answer the prayers of men. He has ordained prayer as a means whereby he will do things through men as they pray, which he would not otherwise do. If prayer puts God to work on earth, then, by the same token, prayerlessness rules God out of the world's affairs, and prevents him from working. The driving power, the conquering force in God's cause is God himself. 'Call on me and I will answer thee and show thee great and mighty things which thou knowest not,' is God's challenge to prayer. Prayer puts God in full force into God's work."
