'In the World' in the Bible

Do not love the world, nor the things in the world. If any one loves the world, there is no love in his heart for the Father.

For the things in the world--the cravings of the earthly nature, the cravings of the eyes, the show and pride of life--they all come, not from the Father, but from the world.

and that no spirit is from God which does not acknowledge this about Jesus. Such is the spirit of the anti-Christ; of whose coming you have heard, and it is already in the world.

As for you, dear children, you are God's children, and have successfully resisted them; for greater is He who is in you than he who is in the world.

Our love will be manifested in all its perfection by our having complete confidence on the day of the Judgement; because just what He is, we also are in the world.
