Augustine of Hippo, on Matt 24:42

“Watch ye therefore, because ye know not what hour your Lord will come.”

“(Ep. 199, 3.) He said this Watch, not to those only who heard Him speak at the time, but to those who came after them, and to us, and to all who shall be after us, until His second coming, for it touches all in a manner. That day comes to each one of us, when it comes to him to go out of the world, such as he shall be judged, and therefore ought every Christian to watch that the Lord’s coming may not find him unprepared; and he will be unprepared for the day of His coming, whom the last day of his life shall find unprepared.”
