'In the World' in the Bible

No, God has chosen what is foolish in the world to shame the wise; God has chosen what is weak in the world to shame what is strong;

God has chosen what is mean and despised in the world ??things which are not, to put down things that are;

let those who mix in the world live as if they were not engrossed in it, for the present phase of things is passing away.

Well then, with regard to food that has been offered to idols, I am quite aware that 'there is no such thing as an idol in the world' and that 'there is only the one God.'

There are ever so many kinds of language in the world, everyone of them meaning something.
