A lot of people are doubtful in this day and age. There are many who are buying propaganda put forth by those with a materialistic world view. Among some of the founders of those proposing a doubtful view of the reliability of the bible was a man named Julius Wellhausen. He was a Doctor in Old Testement theology, later went to study Islam and eventually moved into New Testament theology. He openly claimed that the Old Testament was not historically accurate and doubted the miracles in the Old Testament ever took place.
Since Wellhausen’s day, many more proofs have become available. One of them is the Mesha Stele also known as the Moabite stone. This is one of the earliest inscriptions refering to YHWH and ancient Israel. On the inscription it discusses the “House of Omri”. 1 Kings chapter 16 discusses Omri and his ascent to power in the nation of Israel.
The Mesha Stele is just one of many examples validating the bible as a historically accurate record of the past. The next time someone doubts the validity of the bible, just tell ‘em “Meshe Stele”!
