“When they therefore were come together, they asked of Him, saying, Lord, wilt Thou at this time restore again the kingdom to Israel? And He said unto them, It is not for you to know the times or the seasons, which the Father hath put in His own power. “-Acts 1:6, 7

It is not for us to know the times and the seasons, and to be able to make a map of the future. There are some great events of the future very clearly revealed. The prophecy is not at all indistinct about the facts that will occur; but as to when they will occur, we have no data. Some think that they have; but our Lord here seems to say that we do not know the times and the seasons, and that it is not for us to know them. I pass no censure upon brethren who think that, by elaborate calculations, they find out what is to be in the future; I say that I pass no censure, but time has passed censure of the strongest kind upon all their predecessors. I forget how many miles of books interpreting prophecy there are in the British Museum; but I believe it amounts to miles, all of which have been disproved by the lapse of time. Some of the writers were wonderfully definite; they knew within half-an-hour when the Lord would come. Some of them were very distinct about all the events; they had mapped them all within a few years. The men who wrote the books, happily for themselves, had mostly died before the time appointed came. It is always wise to pitch on a long period of prophecy, that you may be out of the way if the thing does not come off; and they mostly did so. There were very few of them who lived to suffer the disappointment which would certainly have come to them through having fixed the wrong date. I let time censure their mistake. God forgave it, for they did it with a desire for His glory. The bulk of them were most sincere students of the Word, and herein are a lesson to us, even though they were mistaken in their calculations; but, beloved, it is not for you to know the times and the seasons. ~ C.H. Spurgeon
