Why didn't Jesus write a book of the Bible?

[Jack Ryan]

If he was on earth and a perfect human, why didn't he write a text himself that outlined everything perfectly, that way it couldn't get muddled by human interpretation. Everything would be more direct and clear and there would be so much less confusion.

[Melinda Mills]

He was fulfilling what was written about him.  He was called the Logos or the Word of God which means spokesman.  He was also called Teacher.  He came to fulfill the law which was already written. Before he went back to heaven he said the holy spirit or remembrancer would bring back to his disciples' minds things they heard him say. That holy spirit would have been poured out by him. They wrote the gospel accounts.  He spoke from heaven to Saul (Paul). He gave the apostle John the Revelation in signs (in a vision).

He had able disciples such as Luke who traced all things things accurately from the beginning and wrote them in logical order. Clearly he did not need to write.
