Azusa Street Revival Reports from the Time

"… So earnest became this little band that, with much fasting, they almost continued day and night for some days, till, indeed, their day had fully come, and as suddenly as on the day of Pentecost, the Spirit fell upon them and filled them, and all began to speak in other tongues as the Spirit gave utterance. But this speaking in other languages was not all, for, indeed, they were filled with all the fullness of God, and all the characteristics of the first Pentecost was manifest. Can any unbiased man doubt as to the source of this strange power, when these humble children of God were waiting only upon Him, seeking for Himself. This was, indeed, the day of small things, and only so in comparison to the promise, that the latter rain is to be much more abundant than the former. ... In these few months from the time the praying, fasting few received the long-sought-for rending of the heavens, and Jesus did baptize them with His Spirit, up till now [October 15, 1906], this work has spread till its influence has reached half around the world. Many of all ages and races, from varied conditions and abilities, from the very young to the octogenarian, those learned and of no education, each alike has received a definite Baptism of the Spirit. From here God has sent those living witnesses for Him up the coast for hundreds of miles across the continent; into China, India, Africa and Jerusalem—each able to speak in any language to whom God sends, using the language thus given of God with absolute perfection." (A.H. Post, in Way of Faith November 8,1906)
　
"The center of this work is an old wooden Methodist church, marked for sale, partly burned out, recovered by a flat roof and made into two flats by a floor. It is un-plastered, simply whitewashed on the rough boarding. Up stairs is a long room, furnished with chairs and three California redwood planks, laid end to end on backless chairs. This is the Pentecostal "upper room," where sanctified souls seek Pentecostal fullness, and go out speaking in new tongues and calling for the old-time references to "new wine." There are smaller rooms where hands are laid on the sick and "they recover" as of old. Below is a room 40 x 60 feet, filled with odds and ends of chairs, benches, and backless seats, where the curious and the eager sit for hours listening to strange sounds and songs and exhortations from the skies. In the center of the big room is a box on end, covered with cotton, which a junk man would value at about 15 cents. This is the pulpit from which is sounded forth what the leader, Brother Seymour, calls old-time repentance, old-time pardon, old-time sanctification, old-time power over devils and diseases, and the old-time "Baptism with the Holy Ghost and fire."
Meetings begin at 10 o'clock every morning and are continued until near midnight. There are three altar services daily. The altar is a plank on two chairs in the center of the room, and here the Holy Ghost falls on men and women and children in old Pentecostal fashion as soon as they have a clear experience of heart purity. Proud preachers and laymen with great heads, filled and inflated with all kinds of theories and beliefs, have come here from all parts, have humbled themselves and got down, not "in the straw," but "on" the straw matting, and have thrown away their notions, and have wept in conscious emptiness before God and begged to be "endued with power from on high," and every honest believer has received the wonderful incoming of the Holy Spirit to fill and thrill and melt and energise his physical frame and faculties, and the Spirit has witnessed to His presence by using the vocal organs in the speaking forth of a "new tongue."
