What does the Bible say about conformity to the world?

The Bible, specifically in Romans 12:2, commands believers not to conform to this world but to be transformed by the renewing of their minds. This refers to the necessity of distinguishing between the pursuits of the ungodly and the calling of a Christian. Believers are not to engage in practices that conflict with their faith, marking them as 'salt and light' in a dark world. True transformation comes from an internal change driven by the Spirit of God rather than the external pressures of society.
