From the day of Pentecost, there has been not one great spiritual awakening in any land which has not begun in a union of prayer, though only among two or three. And no such outward, upward movement has continued after such prayer meetings have declined. It is in exact proportion to the maintenance of such joint and believing supplication and intercession that the Word of the Lord in any land or locality has had free course and been glorified.
