Barbour and Miller with their religious ideas were two men that had a profound influence in formulating C.T.Russell`s own ideas about the religion he formed the "International Bible Student`s Association" and not the "Jehovah`s Witness" religion that J.F.Rutherford formed .
Joseph F.Rutherford poached the members of the I.B.S.A.away to form the J.W.religion, and isn`t that where most of the members of the J.W.religion come from ,that is being poached away from other existing christian religions ?
In their heyday/glory day`s of growth ,by far the majority of conversions to the J.W.religion came from Christendoms religions ,Roman Catholic ,Church of England ,and other protestant churches .
Very,very,very few conversions were ever made from non christian religions .
In fact Jehovah`s Witnesses to this day have made little to no impact in "witnessing" in Asian ,and Islamic countries that covers about a third of the worlds population .
