Worldliness

Everything in this world has been given to us by God, and is meant for our use.  Indeed, everything is meant for our enjoyment.  Everything is made and created by God, therefore obviously all such things are not only good but are perfectly legitimate for the Christian man.  The use of these things becomes worldliness when we allow things that are perfectly right and legitimate in themselves to take too much of our time, to much of our attention, too much of our interest, too much of our enthusiasm.

This applies to literature, art, music, games — anything you like to think of. … But it becomes worldliness if it absorbs us too much.  If my interest in these things becomes central in my life, and takes the first place, or drives out the spiritual and my concentration on the eternal, then I am guilty of worldliness.
