No treatment of the subject How to Pray would be at all complete if it did not consider the place of prayer in revivals.
The first great revival of Christian history had its origin on the human side in a ten-day prayer-meeting. We read of that handful of disciples, "These all with one accord continued steadfastly in prayer." (Acts 1:14, R.V.) The result of that prayer- meeting we read of in the 2nd chapter of the Acts of the Apostles,
"They were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance." (v.4) Further on in the chapter we read that "there were added unto them in that day about three thousand souls." (v.41,R.V.) This revival proved genuine and permanent. The converts "continued steadfastly in the apostles' teaching and fellowship, in the breaking of bread and the prayers."(v.42,R.V.) "And the Lord added to them day by day those that were being saved." (v.47,R.V.)
Every true revival from that day to this has had its earthly origin in prayer.
