Jehovahs witnesses are prominent in already established "christian " lands , lands that have already been "witnessed" to and converted by christendoms religions ,often centuries before.
So Jehovahs Witnesses have not opened new grounds for their evangelism /witnessing , they are just following in the footsteps of missionaries that have gone on before them and have laid the groundwork for them .
They, the JW`s , come along and poach those of christendoms converts from already established christianised nations and then claim they have witnessed to the world .
When in fact all they have done is changed one brand of christianity to another brand of christianity .
They have not made any in-roads at all .
Italy , Brazil , Mexico ,Spain ,Australia ,USA ,UK ,Ireland ,Canada, just to name a few are already christianised countries as a result of christendoms missionaries .
Where is the phenonemal growth in countries like Bangladesh , Pakistan ,Indonesia, China, India ,Saudia Arabia , Quatar , Phillipines , Jordan , etc,etc,.
Their is no growth in any of these lands and the majority of inhabitants of these countries have never heard of Jehovh or his witnesses., in fact in many of them they dont even exist.
