I advise them, for another thing, if they want to come out from the world, to watch against a sour, morose, ungenial, gloomy, unpleasant, bearish demeanour, and never to forget that there is such a thing as "winning without the Word." (1 Peter iii. 1.) Let them strive to show unconverted people that their principles, whatever may be thought of them, make them cheerful, amiable, good-tempered, unselfish, considerate for others, and ready to take an interest in everything that is innocent and of good report. In short, let there be no needless separation between us and the world. In many things, as I shall soon show, we must be separate; but let us take care that it is separation of the right sort. If the world is offended by such separation we cannot help it. But let us never give the world occasion to say that our separation is foolish, senseless, ridiculous, unreasonable, uncharitable, and unscriptural. III. In the third place, I shall try to show _what true separation from the world really is_. I take up this branch of my subject with a very deep sense of its difficulty. That there is a certain line of conduct which all true Christians ought to pursue with respect to "the world, and the things of the world," is very evident. The texts already quoted make that plain. The key to the solution of that question lies in the word "separation." But in what separation consists it is not easy to show. On some points it is not hard to lay down particular rules; on others it is impossible to do more than state general principles, and leave every one to apply them according to his position in life. This is what I shall now attempt to do. (_a_) First and foremost, he that desires to "come out from the world, and be separate," _must steadily and habitually refuse to be guided by the world's standard of right and wrong_.
