"The book Dispensational Truth: God’s Plan and Purpose for the Ages (1918), containing over 115 charts and other illustrations, is considered a classic and continues to be reprinted today. Larkin wrote a number of other books including commentaries on Daniel and Revelation, which also contain intricate charts and drawings."
"During the last few years of Larkin’s life, his works became so popular that he left the pastorate to devote all his time to writing."
Who was Clarence Larkin?
I think that my friend showed me one of his books, He is a fundamentalist, wasn't he? Isn't Darby considered to be the father of modern dispensationalism? These ideas were at the Niagara Bible Conference from 1883 to 1897 at Niagara Falls.
In 1883 a group of Christian bible scholars met for the first time at Niagara-on-the-Lake, Ontario, near Niagara Falls and established the principles of Christian fundamentalism. It was here that the Niagara Bible Conference gathered every year from 1883 through 1897 (with the exception of 1884). It met at the Queen's Royal Hotel and its pavilion. James Brooks, in his Truth magazine describes the meeting of 1892 as one
"more largely attended than ever before. Often every seat in the pavilion was occupied, and the porches were filled with eager hearers of the Word. The place too becomes more beautiful as the years go by, and it would be difficult to find a spot better suited to the quiet and prayerful study of the Sacred Scriptures. The building in which the Conference meets, overlooking Lake Ontario and the River Niagara, and surrounded by green trees, is secluded from the noise of the world; and so excellent were the arrangements for the accommodation of the guests, both in Queen's Royal Hotel and in the boarding houses of the village, that not a word of complaint was heard from any one." Some of the scholars who were present, known as the founding fathers of Fundamentalism, were W.E. Blackstone, Charles Erdman, James H. Brookes, William Moorehead, A.J. Gordon, A.C. Dixon, C.I. Scofield, and J. Hudson Taylor (who founded the China Inland Mission).
