Acts 1:7

It is not for you to know - The question of the apostles respected the time of the restoration; it was not whether he would do it. Accordingly, his answer meets precisely their inquiry; and he tells them in general that the time of the great events of God’s kingdom was not to be understood by them. They had asked a similar question on a former occasion, Matthew 24:3, “Tell us when shall these things be?” Jesus had answered them then by showing them that certain signs would precede his coming, and then by saying Matthew 24:36, “But of that day and that hour knoweth no man, no, not the angels of heaven, but my Father only.” God has uniformly reproved a vain curiosity on such points, 1Th 5:1-2; 2 Peter 3:10; Luke 12:39.

The times or the seasons - The difference between these words is, that the former denotes any time or period that is indefinite or uncertain; the later denotes a fixed, definite, or appropriate time. They seem to be used here to denote the periods that would mark or determine all future events.

The Father hath put ... - So entirely had the Father reserved the knowledge of these to himself, that it is said that even the Son did not know them. See Mark 3:32, and the notes on that place.

In his own power - That is, he has fixed them by his own authority, he will bring them about in his own time and way; and therefore it is not proper for people anxiously to inquire into them. All prophecy is remarkably obscure in regard to the time of its fulfillment. The reasons why it is so are such as the following:

1. To excite people to watch for the events that are to come, as the time is uncertain, and they will come “like a thief in the night.”

(2)As they are to be brought about by human agency, they are so arranged as to call forth that agency. If people knew just when an event was to come to pass, they might be remiss, and feel that their own efforts were not needed.

(3)The knowledge of future scenes of the exact time, might alarm people, and absorb their thoughts so entirely as to prevent a proper attention to the present duties of life. Duty is ours now; God will provide for future scenes.

(4)Promises sufficiently clear and full are therefore given us to encourage us, but not so full as to excite a vain and idle curiosity. All this is eminently true of our own death, one of the most important future scenes through which we are to pass. It is certainly before us; it is near; it cannot be long delayed; it may come at any moment. God has fixed the time, but will not inform us when it shall be. He does not gratify a vain curiosity; nor does he terrify us by announcing to us the day or the hour when we are to die, as we do a man that is to be executed. This would be to make our lives like that of a criminal sentenced to die, and we should through all our life, through fear of death, be subject to bondage, Hebrews 2:15. He has made enough known to excite us to make preparation, and to be always ready, having our loins girt about and our lamps trimmed and burning, Luke 12:35.
