'In the World' in the Bible

Love not the world, nor the things in the world. If any one love the world, the love of the Father is not in him;

because 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 which does not confess Jesus Christ come in flesh is not of God: and this is that power of the antichrist, of which ye have heard that it comes, and now it is already in the world.

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