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.
In this godless world we all should remember that man shall not live by bread alone, but by every word going forth through the mouth of God Which He has provided for the whole world in many Bible translations. Nobody may forget that in whatever language the Bible is inspired by God and as such protected by God's Power so that it can be useful for every person on earth for teaching, for reproof, for correction, and for training in righteousness, in such a way that the person dedicated to God may be capable and equipped for every good work.
