Some have claimed that John chapter 21 of John’s Gospel was written by a different hand than the apostle John whom they claim only wrote John 1-20. They support this, in part, because the last verse of chapter 20, John 20:31 is in the form of a conclusion, and John 21:24-25 refers to the author of the gospel in the third person (“We know that his testimony is true”).
It is because of the printing press that all books became affordable, and that includes the Bible. Humanity is indebted to the Gutenberg printing press. He mechanized printing and greatly contributed to the world. Bible's today can be bought affordably today by the millions for missionary work around the world. As of October 2019, the full Bible has been translated into 698 languages, the New Testament has been translated into an additional 1,548 languages and Bible portions or stories into 1,138 other languages.
