'In the World' in the Bible

Love not the world, neither the things that are in the world. If any man love 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 vain glory of life, is not of the Father, but is of the world.

and every spirit that confesseth not Jesus is not of God: and this is the'spirit of the antichrist, whereof ye have heard that it cometh; and now it is in the world already.

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