'People Of This World' in the Bible

The master commended the dishonest manager because he acted shrewdly. For the people of this world are more shrewd in dealing with their contemporaries than the people of light.

Jesus said to them, “The sons of this [world and present] age marry and [the women] are given in marriage;

not meaning the immoral people of this world, or the greedy ones and swindlers, or idolaters, for then you would have to get out of the world and human society altogether!
