The millennium you folks attempt to represent is skewed. You believe Zechariah 12:10 is a yet future millennial prophecy. Yet, it is clearly fulfilled in John 19 (as stated),
You believe Isaiah 11 is also representative of a millennial period. Yet, Paul, in Romans 15:12 refers to Isaiah 11:10 in reference to the Gentiles being saved in his time frame...
It is the same "in that day" of Isaiah 10:20, 10:27, and 11:11...
Isa 10:20 And it shall come to pass in that day, that the remnant of Israel, and such as are escaped of the house of Jacob, shall no more again stay upon him that smote them; but shall stay upon the LORD, the Holy One of Israel, in truth.
Isa 10:21 The remnant shall return, even the remnant of Jacob, unto the mighty God.
Isa 10:22 For though thy people Israel be as the sand of the sea, yet a remnant of them shall return[/b]: the consumption decreed shall overflow with righteousness.
Isa 10:23 For the Lord GOD of hosts shall make a consumption, even determined, in the midst of all the land.
Paul quotes from this Isaiah text in Romans 9:27:
Romans 9:27 - Esaias also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved:
And then in regard to the future prophesied remnant, Paul drops the anti-dispensational bomb of:
Romans 11:5 - Even so then at this present time also there is a remnant according to the election of grace.
For the most part, the futurist millennium is representative of the Gospel period. The fountain of living water is the same fountain from Zechariah 13:1.
...and still no one addresses why the apostles illuminate the hundreds of OT Scriptures (promises to Israel) as being applied to the new covenant body of Christ...
The church is the FULFILLMENT of the promises made to Israel - Jew and Gentile in one body in Christ (the Jewish Messiah).
Do you outright deny that John 19:37 (Calvary) is the fulfillment of Zechariah 12:10?
Yes or no?
