After 131 years of preaching around the world. Its a losing battle. There are fewer people today in the US that know witness doctrine or what witnesses would call "the good news of the kingdom". No one I work with has ever even talked to a witness and this is in the most witnessed to country in the world except maybe St. Helena. W
Witnesses have ignored the social changes that have taken place since 1960. Women in the workplace being the main one. They refuse to embrace technology to spread "the truth".
The muslim, hindu and buddhist world are untouched, maybe 1% have heard witness doctrines.
Matt. 24:14 says, i believe, this good news of the kingdom will be preached in all the inhabited earth, and then the end will come. if all of the bible is true, then we are thousands of years away from the end.
