II. Let us notice, in the second place, the principle upon which the apostle founds this decision. It is given in the text--"This I say, brethren, the time is short: it remaineth that both they that have wives be as though they had none," "for the fashion of this world passeth away." Now observe here, I pray you, the deep wisdom of this apostolic decision. In point of fact it comes to this: Christianity is a spirit, not a law; it is a set of principles, not a set of rules; it is not a saying to us--You shall do this, you shall not do that--you shall use this particular dress, you shall not use that--you _shall_ lead, you shall _not_ lead a married life--Christianity consists of principles, but the application of those principles is left to every man's individual conscience. With respect not only to this particular case, but to all the questions which had been brought before him, the apostle applies the same principle; the cases upon which he decided were many and various, but the large, broad principle of his decision remains the same in all. You may marry, and you have not sinned; you may remain unmarried, and you do not sin; if you are invited to a heathen feast, you may go, or you may abstain from going; you may remain a slave, or you may become free; in _these things_ Christianity does not consist. But what it does demand is this: that whether married or unmarried, whether a slave or free, in sorrow or in joy, you are to live in a spirit higher and loftier than that of the world. The apostle gives us in the text two motives for this Christian unworldliness. The first motive which he lays down is this--"The time is short." You will observe how frequently, in the course of his remarks upon the questions proposed to him, the apostle turns, as it were entirely away from the subject, as if worn-out and wearied by the comparatively trivial character of the questions--as if this balancing of one earthly condition or advantage with another, were but a solemn trifling compared with eternal things. And so here, he seems to turn away from the question before him, and speaks of the shortness of time. "The time is short!"
