Complete This Sentence: The Bible is...

After a recent conversation with a friend I have been thinking about the Bible, and what role it plays in the life of a person with faith in Christ. It seems to me that people run into all sorts of problems when the teachings of the Bible collide with how they think life should go. For them, having simple faith in Jesus is easier than accepting the Bible as the final authority in all matters of life, especially when the teaching of Scripture differ from the prevailing popular opinion.

With that in mind I have been trying to put together a definition of the what the Bible is. My goal is for the definition to be as brief, yet as all encompassing as possible. It also has to be intelligible for the non-Christian - even if it is not accepted or believed. Here's what I have so far:
The Bible is God's Word, that is, it is a collection of multiple genres of writing (historical, judicial, biographical, prophetic, poetic, etc.) which all combine to tell ONE story, the story of a trinitarian God:

1) creating all that is;
2) enduring the rebellion of humanity;
3) initiating and completing a plan of redemption for the fallen;
4) and restoring all things for the glory of Himself and the ultimate happiness of humanity.

The words of the Bible were written, collected and preserved under the inspiration and guidance of the Holy Spirit, without error in their original form, and currently serve as the baseline for all faith in Jesus Christ and the final authority on ALL matters for those who claim to know and be known by Jesus Christ.
