Have you encountered anyone who come along saying a "good news" about a new finding. He will ask you "Whats his name?", if you say "Allah" he will say "No, it is a title, not a name!", and he will repeat "what is his name?" and if you fail to answer he will say his name is JHWH. He will pronounce it according to his preaching either "Jehowah", "Yehowah" ... "Yahuwah". And he will reason for his finding. (Remember unlike other bibles the bible they carry is one of their own and it is full of this name 'Jehowah'. Don't be carried away with that!)
If you are quite good in your religious preaching and if you are good at tackling them please do so with Beautiful preaching and Tactfulness. If you need further reading, please feel free to download these material and master them.
But if you don't have time to deal with these people. And no knowledge in the subject. Please try to master these verses from the bible. And offer them whatever the poison you have at home. Any thing; even run rat or run bug will do!
If you can't remember these verses at least try to remember "Mark 16: 15-18" and ask them to open their bible and read it for you. They will run away like what rats and bugs do. but never to be returned. Sometimes they may inform their fellow members too not to visit your home. ;)
So, the bible reads,
15 He said to them, “Go into all the world and preach the good news to all creation. 16 Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. 17 And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; 18 they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.”
DON'T FORGET THE BOTTLE OF RAT KILLER OR BUG KILLER!
