What does the Bible say about the mind of the flesh?

The mind of the flesh is depicted in Scripture as a reflection of fallen human nature, collecting ideas and beliefs throughout one's life that ultimately lead away from the truth of God. This accumulation creates a worldview that is often centered on works acceptance with God, viewing righteousness as something to be earned rather than a gift bestowed by grace. In the book of Joshua, the city of Debar symbolizes these misguided concepts, where people hold onto their traditions and efforts while ignoring the sovereign grace of God that alone can save. A proper understanding of the mind of the flesh helps to reveal how deeply entrenched our tendencies are toward self-reliance and how we must confront these ideas to truly embrace the grace of Christ.
