Question: "Why isn't the Bible in chronological order?"
Answer: The books of the Bible are primarily divided by the type of literature. For example, Genesis through Esther are primarily historical, Job through Song of Solomon are poetry, Isaiah through Malachi are prophecy. Similarly, Matthew through Acts are historical, Romans through Jude are letters to churches or individuals, Revelation is prophecy. Within the type of literature, the books of the Bible are in basic chronological order. For example, Isaiah's prophecies occurred before Jeremiah's prophesies.
The Bible not being in chronological order can sometimes make studying the Bible difficult. That is why chronological Bibles can come in so handy. A chronological Bible actually puts the content of the Bible in chronological order. As an example, Isaiah ministered during the times of the kings. So, a chronological Bible puts Isaiah’s prophecies in the appropriate place in the books of 1 and 2 Kings. A chronological Bible also takes the four Gospels and attempts to put all of the events in order.
