A strong evidence for the Bible’s textual reliability is its internal consistency. Many people wonder why this is big deal, since many books are internally consistent, but what they fail to understand at first glance is that the Bible is not just some small book written by one person.
The Bible is a collection of sixty-six different documents, written by approximately forty different authors, in three different languages (Hebrew, Greek, and Aramaic), spanning roughly 1,500 years, from a multitude of countries (across three continents (Africa, Asia, and Europe), from various educational and cultural upbringings (e.g., doctors, shepherds, fishermen, intellects, historians, and pharisees) all of which would be thought to answer life’s important issues completely differently.
Based on this information we would expect to find incredible differences, variances, and contradictions within these collected writings. But the Bible is completely harmonious and reliable without any real contradictions within its pages. Many who have claimed that there are internal problems, have had their complaints put to rest by scholars who understand the time periods of the writings as well as the society at the time.
