The Bible is a true (genuine) testimony of the religious journey of the Jewish people, with an additional true (genuine) account about Jesus and a record about (plus directives for) the early Christian church. The book is entirely Jewish, and 2 out of 66 books were written by a "gentile" (Luke) thereby emphasizing the shift towards an even more universal outlook upon the world. The Bible is of course also a book of faith - in that sense a search for eternal truth, although our own, inevitable human interpretations always make almost impossible any direct truth claim (e.g. the Bible may be entirely true in the spiritual realm of things yet we are always humans so our own, culture-drenched applications and interpretations of what we read in the Bible cannot be identified with "bible truth") - in other words, all thought about "truth" makes true people humble, and careful with their claims. Besides the historical and religious challenge of the truth-finding mission, the Bible also challenges us through its embedded philosophical, social / cultural, literary etc. accounts.
