Our citizenship is in heaven, which means our earthly lives should reflect heavenly principles. The separation between mortality and immortality is incredibly thin, and believers don't experience death as we fear it—they transition to immortal reality with Jesus. Earth isn't the opposite of heaven but a shadow of it, corrupted by sin. Heaven is a physical place with streets, nations, and beautiful materials beyond our imagination. Living with this heavenly perspective transforms our earthly experience, allowing us to exercise our God-given authority and live with joy despite circumstances.
