This sermon begins with the prophecy relating to the last days, the days of the Messiah, when his kingdom should be set up in the world, at the latter end of the Mosaic economy. In the last days of the earthly Jerusalem, just before the destruction of it, this heavenly Jerusalem should be erected, Heb. xii. 22; Gal. iv. 26. Note, Gospel times are the last days. For 1. They were long in coming, were a great while waited for by the Old-Testament saints, and came at last. 2. We are not to look for any dispensation of divine grace but what we have in the gospel, Gal. i. 8, 9. 3. We are to look for the second coming of Jesus Christ at the end of time, as the Old-Testament saints did for his first coming; this is the last time, 1 John ii. 18.
