'In the World' in the Bible

Do not love the world, nor the things in the world. If anyone loves 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 that does not confess that Jesus Christ has come in the flesh is not of God. And this is the antichrist you heard is coming, and even now is already in the world.

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