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

The conquest of the mind is a vital theme in Scripture, particularly in Romans 12:1-2, where Paul urges believers to be transformed by the renewing of their minds. This transformative process begins with the realization that, prior to salvation, our minds are ruled by human wisdom and self-centeredness. Just as the city of Kiriath-Sephir represents man’s ideas of morality and righteousness, our thoughts and ways must be conquered by the truth of the gospel, which is the power of God unto salvation. This change in mindset is not merely about external behavior but is rooted in an inward change initiated by God through Christ's work on the cross.
