'In the World' in the Bible

Love not the world, nor the things that are in the world; for if any one love the world to excess, 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 of the world.

and every spirit that doth not confess Jesus Christ, who is come in the flesh, is not of God: and this is that spirit of antichrist, which ye have heard was coming, and is already in the world.

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