Concluding it might be difficult to proof the existence of god it is even more difficult to proof there does not exist a Causer of everything.
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 mankind's history there can be found natural theology which is generally characterized as the attempt to establish religious truths by rational argument and without reliance upon alleged revelations. Newt to it we may find lots of name-Christians trying to proof God exist but for them Jesus being God, others can see that their idea of God being Eternal, Immaterial, Transcending space, The Creator and Designer of the universe, Omnipotent, Omniscient, The unique greatest possible Being, does not fit at all their Jesus-god. Many people putting 2 and 2 together decide then wrongly because those qualities not fitting Jesus, he is not being able to be God but then there than also not being a Supreme 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.
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.
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.
Narrations and stories about men, women and peoples are delivered to mankind to bring a message of love and hope and we can see that by the centuries that passed, not much is changed to the words of those written documents or books and copied by many scribes who were serious about bringing over the right words. As the system announced in the Scriptures rests exclusively on the ground of being from Divine revelation, one might suppose that the deists and sceptics together with their coadjutors the rationalists, in thus rejecting the absolute foundation of Scripture revelation, need not give themselves any further trouble of "criticizing them." The credibility of the declarations of the prophets, Jesus and his disciples is greatly corroborated and rendered in a high degree probable. It will appear unwarrantable to charge men so far surpassing the best and most learned teachers of their age, with such a degree of enthusiasm or villainy, as must be ascribed to them, if their pretensions to a divine influence were either a delusion or in imposture.
Contrary to the sayings of KJV-only people, God has given His Word to all people in whatever language they speak and for eternally shedding light on His righteousness and honesty, His Word never telling lies. The Supreme Power also enables us to compare His Word like we can find it in print these days, with the ancient writings and original manuscripts which have been discovered by archaeologists after the 17th century.
KJV-only people often forget that in the many Bible Translation committees, all over the world, can be found many serious honest people who like to do justice to the Word of God. Several brainstormers from all sorts of religious groups often work together as a team to sit down to do some good bible hermeneutics for getting the best contemporary words placed in good readable and understandable phrases.
We may not forget that language is always changing and that written language fossilizes it and makes it stop changing. English imperialism or a megalomania might be at the source of some English speaking people considering their "King James Version" to be the only true and correct Bible translation, while depicting all other English translations as false and misleading versions. Though the world should know that God is mightier than all people and is strong enough Himself to protect His own Word so that in many other languages, but also in English, many different useful and correct bible translations may be offered at the contemporary book-store. some of the many English versions are presented here.
We may not forget that language is always changing and that written language fossilizes it and makes it stop changing. The Bible, especially the King James Version, has been very influential on keeping language the same because it has been so widely read, but even there we must be aware that certain words have changed and that today certain phrases in spoken as well as written English may be brought differently than the 1611 version. King James Version people are people who work against the Will of God, not willing to recognise that today we may have people with more and better knowledge of God's Holy Word than those of the 17th century. By not willing to accept the advancement which is made in Bible archaeology KJV-only people become adversaries of God.
