The book of Judges chronicles the reigns of twelve leaders (judges) whose temporary leadership over the confederation of Israelite tribes was both civil and military.
The book of Judges covers the approximate 400-year historical period from Joshua’s death (end of book of Joshua) to the establishment of a king over the Israelite tribes (book of 1 Samuel).
During this time Israel’s national and spiritual life descended into chaos and apostasy. As a result the Israelite tribes fought with their neighboring nations to retain control over the promised land that they had conquered and possessed as described in the book of Joshua.
The leaders in Judges demonstrated a variety of leadership strategies. In spite of the unique and sometimes questionable approaches to leadership of these judges, there is an underlying theme in the book of Judges that has relevance for our individual and collective spiritual lives.
The lesson to be gained from the book of Judges is that like the Israelite tribes possessing the promised land, we have to fight to maintain any spiritual victories we have achieved in our lives.
