Russell said he was going out there and gathering the one or two "truths" that some religions had "saved" to be gathered into one place again when Jesus came back to take possession of the kingdom. He said he was only looking for the people who would really be ruling with Christ in heaven.
There was no push to find or convert non-anointed people because soon (1914) god would end wickedness, government infrastructure, commercial infrastructure and religious infrastructure, the big three (trinity?).

THE present world system under Satan’s control has three principal elements that are manipulated by “the god of this world.” These are political rulership, big business control and influence, and religion. Over the millenniums of history, these three factors have been the constants of virtually every ruling system. Which of these powerful forces is symbolized by “the mother of the harlots”?—2 Corinthians 4:3, 4, The Jerusalem Bible; Revelation 12:9; 17:5.
