'World' in the Bible

For our glory is in this, in the knowledge which we have that our way of life in the world, and most of all in relation to you, has been holy and true in the eyes of God; not in the wisdom of the flesh, but in the grace of God.

Because the god of this world has made blind the minds of those who have not faith, so that the light of the good news of the glory of Christ, who is the image of God, might not be shining on them.

So if any man is in Christ, he is in a new world: the old things have come to an end; they have truly become new.

That is, that God was in Christ making peace between the world and himself, not putting their sins to their account, and having given to us the preaching of this news of peace.

For the sorrow which God gives is the cause of salvation through a change of heart, in which there is no reason for grief: but the sorrow of the world is a cause of death.
