This book has been written with a deep impression that the place and power of prayer in the Christian life is too little understood. I feel sure that as long as we look on prayer solely as the means of maintaining our own Christian life, we shall not know fully what it is meant to be. But when we learn to regard it as the highest part of the work entrusted to us, the root and strength of all other work, we shall see that we need nothing more than to study and practice the art of praying.
If I have succeeded in pointing out the progressive teaching of our Lord in regard to prayer, and the distinct reference of His wonderful promises of His last night to the works we are to do in His name – to the greater works and the bearing of much fruit – we shall all admit that only when the church gives herself up to this holy work of intercession can she expect the power of Christ to manifest itself on her behalf. I pray that God will use this book to explain to some of His children the wonderful place of power and influence that He is waiting for them to occupy and that a weary world is waiting for too.
