There is a mighty lot of difference between saying prayers and praying. -John G. Lake
Those who know God the best are the richest and most powerful in prayer. Little acquaintance with God, and strangeness and coldness to Him, make prayer a rare and feeble thing. -E. M. Bounds
"I would rather teach one man to pray than ten men to preach." -Charles Spurgeon
"Prayer is the acid test of devotion." -Samuel Chadwick
"Our prayers lay the track down which God's power can come. Like a mighty locomotive, his power is irresistible, but it cannot reach us without rails." -Watchman Nee
"Since the days of Pentecost, has the whole church ever put aside every other work and waited upon Him for ten days, that the Spirit's power might be manifested? We give too much attention to method and machinery and resources, and too little to the source of power." -Hudson Taylor
Through the plan of prayer, God actually is inviting redeemed man into full partnership with Him; not in making the divine decisions, but in implementing those decisions in the affairs of humankind. Independently and of His own will, God makes the decisions governing the affairs of earth. The responsibility and authority for the enforcement and administration of those decisions, He has place upon the shoulders of the church. -Paul E. Billheimer
All things else being equal, our prayers are only as powerful as our lives. In the long pull we only pray as well as we live. - A.W. Tozer
