We may allow that those who had been present at the Ascension, and had heard the words of the angels declaring that "this same Jesus should so come as they had seen Him go into heaven" (Acts i. 11), might expect His return to judge the world to be not far distant. But, in whatever they say in reference thereto, their main concern is that men should be ready. "In such an hour as ye think not the Son of man cometh," is the ground-text of all their exhortations. Now had arrived the fulness of the time (Gal. iv. 4) in which God had sent forth His Son, born of a woman; and if we take the verb of St. Peter's sentence ἥγγικε, "has come near", we feel that he viewed the new era on which the world had entered in this light. And so did the other Apostles. One says, "Now once in the end of the ages hath Christ been manifested" (Heb. ix. 26); another teaches that things of old "were written for our admonition, upon whom the ends of the ages are come" (1 Cor. x. 11). God has spoken aforetime in many portions and in many ways, but in the end of these days He hath spoken in His Son (Heb. i. 2). All things are now summed up in Christ; He is the end of all things. Prophecy, type, sacrifice, all have passed away. There will come no new revelation; no word more will be added to the Divine book. Its lessons will find in each generation new illustrations, new applications, but will admit no change of form or substance. The Christian dispensation, be it long or short, is the last time; it will close with the Second Advent. And continual preparedness is to be the Christian's attitude. And this is the purport of St. Peter's next exhortations, which are as forceful to-day as they were eighteen hundred years ago. _Be ye therefore of sound mind._ Exactly the counsel which should follow the previous lesson. It was misinterpreted at first, as it has been since. We know how unwisely the Thessalonians behaved when they had been told by St. Paul, "The day of the Lord so cometh as a thief in the night" (1 Thess. v. 2). The Apostle learnt that they were sorely disturbed, and wrote them a second letter, from which we can gather how far they had wandered from soundness of mind. At first the Apostle speaks gently: "Be not quickly shaken from your mind, nor yet be troubled, either by spirit, or by word, or by epistle as from us, as that the day of the Lord is now present" (2 Thess. ii. 2). But soon he shows us how the excitement had operated. Some among them had begun to walk disorderly, apparently thinking that they might live upon the community, working not at all, but being busybodies. These made, no doubt, the approach of the day of the Lord their pretext. St. Paul bids such men in quietness to work and eat their own bread. To be found at their duty was the best way of preparing for the end.
