The lost person has an entirely different orientation than we do. They are Earth-dwellers.
Earth-dwellers live for their APPETITES Philippians 3:19a "Their destiny is destruction, their god is their stomach, and their glory is in their shame. Their mind is on earthly things."
Earth-dwellers lived for their APPEARANCE Philippians 3:19a "...and their glory is in their shame. Their mind is on earthly things."
Earth-dwellers live for their ADDRESS Philippians 3:19c "Their mind is on earthly things." Did you know that in the book Revelation the word the Holy Spirit uses to describe lost people most often is "earth-dwellers", people who only live for the here and now. Paul said that believers are totally different. We are Citizens of Heaven as Paul taught them in Philippians 3:20. What would this communicate to these saints? Citizens of Rome were little fragments of Roman society. So when Paul compared being in Christ to being a Roman they understood what he meant. Do we?
