Charles H. Spurgeon on Psalms 90:4

For a thousand years in thy sight are but as yesterday when it is past. A thousand years! This is a long stretch of time. How much may be crowded into it, —the rise and fall of empires, the glory and obliteration of dynasties, the beginning and the end of elaborate systems of human philosophy, and countless events, all important to household and individual, which elude the pens of historians. Yet this period, which might even be called the limit of modern history, and is in human language almost identical with an indefinite length of time, is to the Lord as nothing, even as time already gone. A moment yet to come is longer than "yesterday when it is past", for that no longer exists at all, yet such is a chiliad to the eternal. In comparison with eternity, the most lengthened reaches of time are mere points, there is in fact, no possible comparison between them. And as a watch in the night, a time which is no sooner come than gone. There is scarce time enough in a thousand years for the angels to change watches; when their millennium of service is almost over it seems as though the watch were newly set. We are dreaming through the long night of time, but God is ever keeping watch, and a thousand years are as nothing to him. A host of days and nights must be combined to make up a thousand years to us, but to God, that space of time does not make up a whole night, but only a brief portion of it. If a thousand years be to God as a single night watch, what must be the life time of the Eternal!
