Daniel 9:24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
So, how can you know Jesus was Messiah, if He didn't "seal up the vision and prophecy"? Which ones of these are yet to be fulfilled?
You realize you can't prove Jesus is Messiah, if He didn't fulfill all Messianic Prophecy. According to you guys it is still unknown if He is Messiah or not, since "He is still working on fulfilling Prophecy". I don't know if you realize, to say that Jesus didn't fulfill all Messianic Prophecies, is to say that Jesus is not Messiah. Because Messiah fulfills all Messianic Prophecies.
Now, the second coming is after the seventy weeks, after all Prophecy is sealed, and after the covenant is confirmed. After Messiah is confirmed, He comes to judge as King those who reject Messiah. Messiah had to be confirmed and fulfilled first in order for Messiah to have legal basis against those who reject Him, because after all Prophecy is sealed, those who reject Messiah are without excuse, since all Prophecy was fulfilled and the covenant confirmed.
