What does the Bible say about the believer's relationship with the world?

In 1 Corinthians 2:14, Paul writes that 'the natural man receiveth not the things of the Spirit of God; for they are foolishness unto him: neither can he know them, because they are spiritually discerned.' This indicates that the world is generally ignorant of the spiritual realities that define the believer's experience. Paul describes believers as being 'unknown' by the world, which often fails to recognize the spiritual struggles, joys, and life of faith that Christians undergo. Furthermore, in John 15:19, Jesus warns His disciples that because they are not of the world, the world will hate them, reflecting a fundamental disconnect between the Christian and secular perspectives. Thus, believers may often feel marginalized or misunderstood as they navigate their spiritual lives in a culture that does not align with their values and beliefs.
