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.
There are people who want us to believe god had to purify Himself but that we ourself do not have to do any works any more or can do whatever we want because God brought salvation to us by His death, though God can not die. By such misleading teaching those 'preachers' are fooling not only themselves but are taking the opportunity away for others to find the Real God of gods and the entrance to the Kingdom of God.
Not many believers may considered wise or powerful according to human standards, or may not being 'well born' or from "blue blood". In the Scriptures may be found many words also from foolish men. Many wrong actions of men are notated in the bible so that people can learn from them. Those foolish things of the world God chose in order that He might put to shame the wise, and the weak things of the world God chose in order that He might put to shame the strong, and the insignificant of the world.
