'Worldly' in the Bible

Brothers, I couldn't talk to you as spiritual people but as worldly people, as mere infants in the Messiah.

That's because you are still worldly. As long as there is jealousy and quarreling among you, you are worldly and living by human standards, aren't you?

Let no one deceive himself. If anyone among you thinks that he is wise in this age, let him become a fool [discarding his worldly pretensions and acknowledging his lack of wisdom], so that he may become [truly] wise.

And I would have you free from worldly anxiety. An unmarried man concerns himself with the Lord's business--how he shall please the Lord;

but the married man is concerned about worldly things, how he may please his wife,

Am I making use of merely worldly illustrations? Does not the Law speak in the same tone?
