'In the World' in the Bible

Love not the world, nor the things that are in the world. If any man loves the world, the love of the Father is not in him.

For all that is in the world, the desire of the flesh, and the desire of the eyes, and the pride of life, is not of the Father, but is of the world.

and whatever spirit confesses not that Jesus Christ came in the flesh, is not from God: and this is the spirit of antichrist, of which you have heard that it comes, and is now already in the world.

You are of God, little children, and have overcome them; because he that is in you, is greater than he that is in the world.
