The answer is: 8 years

2 Kings 22:1

It's pretty astonishing that Josiah began his reign at just 8 years old! Can you imagine a child that young in charge of running a kingdom? Josiah was the 16th king of Judah, and under his rule, a major reformation took place, which beautifully highlights the concept of change often being rooted in a pure heart, regardless of age. Interestingly, Josiah’s story offers powerful insights about leadership and spiritual renewal.

Despite his young age, he was influenced by the faithful teachings of his court and especially his grandfather, King Hezekiah, known for doing what was right in the eyes of the Lord. Just as His inclusive reign echoed the reformative teachings of the past, Josiah renewed covenant laws after the discovery of the Book of the Law in the Temple, initiating significant changes. His actions cultivated a reverent atmosphere amidst what could have been a complacent age in the kingdom.

Moreover, it's fascinating to note that other Biblical figures also took on leadership roles early in life. For example, Samuel was just a boy when he was called by God to be a prophet. The text implies that these youthful figures, often connected through close ties with the Divine, demonstrated that genuine faith and commitment can prevail across generations and ages.

Josiah remains a remarkable example of youthful leadership, emphasizing it's not simply years lived but actions taken along the way that define a meaningful legacy.
