'In the World' in the Bible

Love not the world, neither 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 lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.

And every spirit that confesses not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, of which you have heard that it should come; and even now already is it in the world.

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