Nineteen centuries of ongoing scholarly examination has yet to overturn the essential composition of the Bible. The texts included were chosen based upon authorship, direct reference by Jesus, His Apostles, and their immediate disciples, among other reasons. Traceability and internal agreement were essential to inclusion. More importantly, God is able to preserve His Word to us.
No new texts may be added to Scripture because Jesus Himself warned us emphatically not to do it once His revelation to John was complete (see Rev 2:18-19).
"If this would be the case, then isn't there a possibility that anybody of us if properly attuned could breathe out the word of God and expand the so called 'All Scripture'?" No one but God is capable of theopneustos. See Jesus' warning about adding to His Word.
Paul used the Greek term theopneustos, a compound word that means 'God-breathed' or 'breathed out by God,' and this tells us that the Scriptures are the creation of God, that they are the words of His breath, His speaking. This is similar in concept to His speaking Creation into existence, except that He created Scripture through men.
"Talking about Christians it is of course important to remember that Jesus and Paul were not Christians because the whole term was not yet even around during their life time. More labels one identifies oneself with less free one is in general and less free to see different interpretative possibilities in particular as every conceptual framework, for example, Christian or atheist narrows one's capability to see clearly. You might most probably disagree with that..."
You're right, I do disagree. The term "Christian" merely means Christ-like. Calling one's self a Christian no more limits one's interpretive skills than labeling someone a "teacher" interferes with their ability to impart knowledge. It's just a term of convenience for identifying a follower of Jesus Christ. Some use the term more loosely than others, but it identifies me with Christ.
"Interpretation is difficult because people have so many prejudices." Interpretation is sometimes difficult because God intended it to be studied carefully by those to whom He gave the Holy Spirit (see 1 Cor 2:12-14 and 1 John 2:20, 27, for example). Jesus made plain the meanings of His parables only to His disciples and deliberately kept everyone else in the dark (see Matt 13:10-15, for example). Proper interpretation is only possible by those who have the Holy Spirit and study the Word carefully.
"One should wash ones eyes clean from all prejudices to see clearly, to interpret clearly without any prejudgments, and vested interests. PERHAPS that was what Jesus meant by becoming again childlike to enter the Reign of Heaven." That's not what it means. Nowhere does Scripture teach that we must remove our prejudices in order to enter the kingdom of God. Jesus interpreted His own words for us so we don't have to guess:
"Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven. Whoever humbles himself like this child is the greatest in the kingdom of heaven." Matthew 18:3-4
Entering the kingdom of heaven requires childlike humility. James and Peter, teaching on salvation and quoting from the Old Testament, said, "God is opposed to the proud, but gives grace to the humble" (James 4:6 and 1 Peter 5:5). Without the childlike characteristic of humility, God will not save us - we will not enter the kingdom of heaven.
