2000 years ago Jesus spoke about such teachers who think they are the only ones who can explain the Bible. Today people should be aware that it is the Scriptures itself that can explain everything and that it is Jeshua, Jesus Christ, whom we should follow as the most perfect teacher.
Christianity is a love affair. Each person calling himself or herself a Christian should live a life of service to God and Jesus, by serving each other, putting the needs of others before our needs, showing to others the love Jesus gave us.
In people saying God knows everything and claiming that Jesus would be God, adversaries of God receive an easy gainsaying danger because they can see how Jesus not at all knew everything, or in case he knows everything than it is clear that Jesus would not have told the truth on more than one occasion and as such would be a liar. The God of Jesus has man given the own possibility to choose what to believe and what to do, therefore it is up to man to make the right choice and to believe in the Only One true God or in the god man has created for himself or to please himself.
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.
