"Why have the people of India ,Pakistan,Bangladesh,China,India,Indonesia,etc.etc. large populations of earth been deprived of this life saving message for two centuries ? """" NOT ANYMORE ...
Because contrary to what have been led to believe by JWs (if you've been one of them) or certain christians groups ... the preaching of the Gospel is for testimony (not conversion) and will be magnified as time closes in (end of the age), the Holy Spirit convicts us of our sinful nature and will lead us to accept Jesus as the Son of God. The Gospel now is reaching people by the billions through Satellite TV ... millions are giving their life to Christ all over the world ... JWs led us to believe that we have to be PERFECT first in order to be acceptable to the Father, but the Bible tell us otherwise, Jesus will finish the good work that has been started in us (the Spirit that comes to dwell in us when we accept Jesus) ... ask God to reveal you, to give you insight into the Parables of the Kingdom of God ... "this life saving message" you refer to... it is for the end of the age ... we may be in that time it may be years in the future ... my Saviour, my dear Lord Jesus, the Sower, He knows...
