'Earthly Things' in the Bible

whose fate is destruction, whose god is their belly [their worldly appetite, their sensuality, their vanity], and whose glory is in their shame—who focus their mind on earthly and temporal things.

For all that is in the world—the lust and sensual craving of the flesh and the lust and longing of the eyes and the boastful pride of life [pretentious confidence in one’s resources or in the stability of earthly things]—these do not come from the Father, but are from the world.
