"If any man love the world, the love of the Father is not in him."2 Timothy 4:10
"For Demas hath forsaken me, having loved this present world"And John 15:19
"If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you."But the perception seems to have become that these verses are primarily about enjoying Secular entertainment media, and such things. While those can be a factor, they are not the point.
The word for World in the verses from John is Kosmos. The Greek etymology of that word implies order, it has been taken to mean "the ordered system of the world".
This is the same word where Satan is called the Ruler of the World. These are about how Satan owns all the nations of the World.
So when you read "Love not the World" remember then The United States of America is part of that world.
For more elaboration read my earlier posts. Patriotic Idolatry and Standing for The National Anthem is Idolatry.
Believes are not Citizens of The World or any Earthly Nation, but of The Kingdom that is NOT of This World.
