The disciples expected that Christ would "come" as King, with a royal presence, and to remove the Romans and thrown down the corrupt temple, all at the same time and soon! It was a disappointment for them it turned not out that way, but they came to understand we could have an even much better future because of what Jesus had done. Though they also became convinced of the necessity to be prepared for the time that Jesus would return and that each believer could add by his effort of preaching, to bring the time closer.
A look at the bible Students and different Jehovah's Witnesses regulations or prescriptions and rules for undergoing baptism.
Always there have been real followers of Jesus who only worshipped his One God, the God of Israel. Many centuries they worked and preached behind closed doors, avoiding persecution and death on the balefire. In fear of the stake for centuries the real followers of God baptised people in their faith, not demanding to be part of one or another church but being part of the Body of Christ.
An invitation to Jehovah's Witnesses who want or did leave the Jehovah's Witnesses organisation. for them there are many other non-trinitarian groups willing to welcome them as brothers and sisters in Christ.
Often a lot of people do not know to differentiate between Christendom, Christianity, religiosity and even limit religiousness to Christians, forgetting that there are many other religious groups who have all sorts of worship.
In the history of Christendom we see many churches which started of as so called cults or so called heretic movements, though many years later they sometimes outgrew their original group and/or became one of the many main churches. Therefore one should be very careful by damning a group or calling ti a cult or sect, when there is not really anything what qualifies it to become called a sect or cult.
Before calling a church or religious group a "cult" or "sect" one should seriously examine and clarify what one means with those qualifications.
Like Richard Dawkins despises religion we see many others reacting strongly against lovers of God, though they do not see zero purpose, zero usefulness, zero value, and zero reason in religion and question why anyone else should either.
We should not be afraid to do research outside of the Bible. There are still many other things to be found, by doing so, that Jehovah’s people have yet to learn. To stop researching our Faith would be a big mistake. If we have “The Truth” than there is nothing to fear from such investigations. The trinitarians who say there is only one Bible the right one are giving several reasons for atheists and people against God to have enough proof to show them they are wrong also in their belief of God, because their sayings or words even do not match the bible words or ancient manuscript words and as such those people give a proof there would not exist a God.
