1 Thessalonians 5:2

"But concerning the times and the seasons, brethren, ye have no need that aught be written unto you. For yourselves know perfectly that the day of the Lord so cometh as a thief in the night." Nothing, as it seems, is so curious, and so fondly prone to pry into things obscure and concealed, as the nature of men. And this is wont to happen to it, when the mind is unsettled and in an imperfect state. Why has he not said that no one knows? why has he not said, that it is not revealed, instead of saying, "Ye have no need that aught be written unto you"? Because in that case he would have grieved them more, but by speaking thus he comforted them. For by the expression, "Ye have no need," as if it were both superfluous, and inexpedient, he suffers them not to enquire. For tell me, what would be the advantage? Let us suppose that the end would be after twenty or thirty or a hundred years, what is this to us? Is not the end of his own life the consummation to every individual? Why art thou curious, and travailest about the general end? But the case is the same with us in this, as in other things. For this reason Christ did not tell it, because it was not expedient. Hear Paul saying, "For yourselves know perfectly that the day of the Lord so cometh as a thief in the night." Not the general day only, but that of every individual. For the one resembles the other, is also akin to it. For what the one does collectively, that the other does partially. For the period of consummation took its beginning from Adam, and then is the end of the consummation; since even now one would not err in calling it a consummation.
