One would think, or I would anyway, that this statement alone is completely contrary to:
Mat_24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
Mar_16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
Now how weird is that...That verse in Jeremiah says NOT to go into all the world and preach the Gospel...That ought to be a major clue to everyone that the verses in Jeremiah are not referring to the Church Age...It says don't teach anyone anything about Jesus, or the Kingdom...Jesus taught the apostles and disciple just the opposite of that...
And then the rest of the verse tells us and Israel why we don't need to go into all the world and preach the Gospel...
for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
HuH??? This is crazy, unless one chooses not to believe Jeremiah...
No need to preach the Gospel, why???
FOR THEY SHALL ALL KNOW ME without hearing the Gospel...Every single one of them...
You have to stuff those pages into a trash burner and load it up with Kerosene and light it with a blowtorch to get rid of that truth...
Jeremiah is not referring to a Christian in any age in those passages...
You are absolutely right that Jer. 31:31-34 and the verses in Mat. & Mark do not refer to the same period. The only way that Jer. 31:31-34 makes sense is to understand there will be a Millennial Kingdom on earth after the Tribulation.
You summed up Walvoord's article beautifully.
As Walvoord wrote:
The amillennial argument breaks down, however, not on the basis of these finer distinctions but the obvious failure in the present age of any literal fulfillment of the covenant with Israel. As in other particulars of prophecy concerning the millennium, a literal fulfillment demands a future millennial dispensation.
