Some of the publichers can give you  a few numbers of some who want to study by phone and arrange for them to have the right book to use for each party. I also study with some of my grandchildren and Gr. grandchildren too.  Incidental witnessing  can be transmitted to addresses on the internt , such as a brief message like" did you know that the plagues of the Exodus were all aimed at the gods of Egypt , to let the Egyptians know about  Jehovah? "

or did your religon teach you what the term Gentile times  were? And who are Gentiles?

 Did you know that only one nation was Gods nation ... only when they obeyed his laws and were founded on his laws.?

Did you know that when Israel rejected Jesus  that Jesus  said :Look your house is abandoned to you" which meant that no longer was God protecting them as his people.

Jehovah told Israel when they were formed as a nation, If you keep my laws and worship only me, I will be your God and you will be my people. So when they did , Jehovah protected that small nation  from being conquered.

Did you know that Armegeddon was based on the happenings of Megeddo  a place where  other nations  plotted an attack against Israel, and then were defeated?

Did you know that  very bad  problems all over the earth  will happen in one generation, and why? Because Satan was confined to the vicinity of the earth before being abbysed and he is very angry , wanting to destroy what he  no longer can rule.  Rev. Ch. 12
