Thought from Today's Old Testament Passage:
[Daniel 9:20-27] [W]hatever uncertainty we may labour under concerning the exact fixing of these times, there is enough clear and certain to answer the two great ends of determining them. [1.] It did serve them to raise and support the expectations of believers. There were general promises of the coming of the Messiah made to the patriarchs; the preceding prophets had often spoken of him as one that should come, but never was the time fixed for his coming until now. And, though there might be so much doubt concerning the date of this reckoning that they could not ascertain the time just to a year, yet by the light of this prophecy they were directed about what time to expect him. And we find, accordingly, that when Christ came he was generally looked for as the consolation of Israel, and redemption in Jerusalem by him, Lu. 2:25, 38.… [2.] It does serve still to refute and silence the expectations of unbelievers, who will not own that Jesus is he who should come, but still look for another. This prediction should silence them, and will condemn them; for, reckon these seventy weeks from which of the commandments to build Jerusalem we please, it is certain that they have expired above 1500 years ago; so that the Jews are for ever without excuse, who will not own that the Messiah has come when they have gone so far beyond their utmost reckoning for his coming. But by this we are confirmed in our belief of the Messiah's being come, and that our Jesus is he, that he came just at the time prefixed, a time worthy to be had in everlasting remembrance.
