1 Corinthians 2:12 Now we received, not the spirit of the world, but the spirit that is from God,
But we are bombarded by the spirit of the world from work mates, school mates, radio, YouTube, internet, computer games, TV shows, worldly music, news channels, advertisement posters, etc.
Ephesians 2:2 in which you at one time walked according to the system of things of this world, according to the ruler of the authority of the air, the spirit that is now at work in the sons of disobedience. 3 Yes, among them we all at one time conducted ourselves in harmony with the desires of our flesh, carrying out the will of the flesh and of our thoughts, and we were naturally children of wrath just as the rest.
Romans 12:2 And stop being molded by this system of things, but be transformed by making your mind over, so that you may prove to yourselves the good and acceptable and perfect will of God.
Who wouldn't like to get out of this system of things if it was possible?
