J. Edwin Orr quotes:

No great spiritual awakening has begun anywhere in the world apart from united prayer.

It is utterly impossible to divorce the story of student awakenings from the course of missions in countries overseas. From the beginning, one of the most immediate and dramatic effects of college revivals has been the recruitment of personnel for the work of Christ abroad.

Whenever God is ready to do something new with His people, He always sets them to praying.

Many ills of the Christian life are due to handicapped beginnings. Too many people are preaching a warped or truncated gospel, and spiritual birth defects are the inevitable result.

The Revival of 1859 helped to lay the foundations of the modern international and interdenominational missionary structureEvery revival of religion in the homelands is felt within a decade in the foreign mission-fields, and the records of missionary enterprises and the pages of missionary biography following I860 are full of clearest evidence of the stimulating effect of the Revival throughout the world.

History is silent about revivals that did not begin with prayer.

God Who delivers us from the guilt of sin through faith in Jesus Christ, is able to deliver the believer from the power of sin as well.

We don't have to convince an unwilling God to come and refresh us with His presence. He's for it. But, He cannot be manipulated. But when sincere hearts who know they cannot do His work nor His will without Him, humbly pray, He will answer.
