Why Are There Gaps in the Bible's Historical Narrative?

That is such a gentle and thoughtful question! The Bible sometimes seems to skip forward in time, and those parts that look like gaps are actually proof of how cleverly the Bible was put together, like a highly specialized, sacred history bookSITI June 28, 1883, page 293.3+1.

Imagine you are reading a special book written only about the family history of a king, tracing how his great kingdom was built over many yearsSITI June 28, 1883, page 293.3. If some years passed where nothing happened that was important to that main goal—like a long period when the king's family was just waiting or serving in another country—the writer wouldn't need to spend many pages describing those quiet timesHBS 394.2.

The Bible is exactly like that; it is not meant to be a diary that records everything that happened every single day, but rather a prophetic history that focuses specifically on the development of God's earthly kingdom and His wonderful plan to save usBHOTV5 55.1+1.

For example, God's people spent many, many years living in Egypt, and later they spent forty years wandering in the desertSITI June 28, 1883, page 293.3. The Bible passes over many of those long years in silence because those periods didn't contribute much to the establishment of the theocracy—which is the main story God wanted toldHBS 394.2. The silence about certain periods shows how steadily the sacred plan was adhered to by the inspired writersSITI June 28, 1883, page 293.3.

The wonderful thing is that the Bible was written by God, who knows all the secrets of the human heart, and He chose only the most important events and truths to share with us Amos 3:7HOMI December 1891, page 269.9. He left out all the things that are unnecessary so that we can focus on the big ideas, like how He saves us from sin and how we can know His willHOMI December 1891, page 269.9.

Even in parts of the Bible that describe big events, like the creation of the world, God used plain and simple language, giving us only the grand outlines of what took place, not every scientific detail Genesis 1:1-5NTMS 37.2+1. This simplicity is part of the book's majestyBHOTV1 13.2.

The story is always continuous and unbroken, focusing on how God helps His children, showing us the results of disobedience and the great rewards of loyaltyHBS 394.2+1. Even the stories of people who lived long ago are important and instructive for us today, because people now are just like the men and women who lived in Bible times, as far as their natural tendencies are concernedGCB June 1, 1913, page 209.1. Because God knows exactly what we need, the history He gave us perfectly fits the cases of all people in all times, without a single unnecessary thingHOMI December 1891, page 269.9.
