I came across this short youtube video titled
Plymouth Brethren & John Nelson Darby Founder Of Dispensationalism & The Pre Trib Rapture Exposed. Very well done with numerous scholars cited. What I found so interesting, especially concerning Darby himself, was that I could almost perfectly substitute WL in place of Darby, with minor changes like inserting "God's Economy" for "dispensationalism."
One can readily see the similarities between these two men, their talents, their rise to prominence in the movement, their attitudes towards others, their views of the church and recovery, etc.
