Christians should live in the world, but not be filled with it. A ship lives in the water; but if the water gets into the ship, she goes to the bottom. So Christians may live in the world; but if the world gets into them, they sink.
Buying, possessing, accumulatingthis is not worldliness. But doing this in the love of it, with no love of God paramountdoing it so that thoughts of eternity and God are an intrusiondoing it so that ones spirit is secularized in the process; this is worldliness.
It has been well said that there is a sin of other-worldliness no less than a sin of worldliness, and Christendom has had a large measure of the former sin as well as of the latter. People have been taught so much about preparing for heaven that they have sometimes become very indifferent workers on earth, and in anticipating the joys of the future world have overlooked the infinite possibilities for good in the world that now is.
