Let us learn secondly from these verses — the exceeding suddenness of our Lord's second coming. We read, "That day will close on you unexpectedly like a trap!" It will come as a trap falling suddenly on an animal, and catching it in a moment — as the lightning flash shining suddenly in the sky, before the thunder is heard — as a thief coming suddenly in the night, and not giving notice that he will come — so sudden, so instantaneous will the second coming of the Son of man be!The precise date of our Lord Jesus Christ's return to this world, has been purposely withheld from us by God. "Of that day and hour — no man knows." On one point however, all the teaching of Scripture about it is clear and unmistakable. Whenever it shall take place — it will be a most sudden and unexpected event. The business of the world shall be going on as usual. As in the days of Sodom, and the days before the flood — men shall be "eating and drinking, marrying and given in marriage." Few, even among true believers, shall be found completely alive to the great fact, and living in a state of thorough expectation.In a moment, in the twinkling of an eye, the whole course of the world shall be stopped. The King of kings shall appear. The dead shall be raised. The living shall be changed. Unbelief shall wither away. Truth shall be known too late by myriads! The world with all its trifles and shadows shall be thrust aside. Eternity with all its solemn realities shall begin. All this shall begin at once, without notice, without warning, without note of preparation. "That day will close on you unexpectedly like a trap!"The servant of God must surely see that there is only one state of mind which befits the man who believes these things. That state is one of perpetual preparedness to meet Christ. The Gospel does not call us to retire from earthly callings, or neglect the duties of our stations. It does not bid us to retire into hermitages, or live the life of a monk or a nun. But it does bid us to live like men who expect their Lord to return! Repentance toward God, faith toward our Lord Jesus Christ, and holiness of conduct — are the only true habitual preparations required. The Christian who knows these things by experience — is the man who is always ready to meet his Lord.
