The Congo Revival that occurred in the 1950's is here told by a missionary that experienced the revival. Rev. David Davies went to the Belgian Congo in the 1930's, and remained there for around 30 years. This lecture about the revival was given to the students at the Bible College of Wales in 1991, while I was a student there. I recorded this message, which is now available at sermonindex.net. You may find it at other places, under other names.
I hope that this tape blesses you as much as it has blessed me over the years.
