We will only advance in our evangelistic work as fast and as far as we advance on our knees. Prayer opens the channel between a soul and God; prayerlessness closes it. Prayer releases the grip of Satan’s power; prayerlessness increases it. That is why prayer is so exhausting and so vital. If we believed it, the prayer meeting would be as full as the church.
