Assertion without Biblical demonstration is assertion without Biblical merit.
That is what YOU did. You cannot quote EVEN ONE New Testament passage that ACTUALLY SAYS what you are claiming.
But MANY Bible passages EXPLICITLY say that the ancient nation of Israel will eventually be brought back to its ancient homeland, and that here will be a world kingdom centered there.
That these scriptures speak of the NATION of Israel is EXPLICITLY stated in Jeremiah 31:35-36:
“Thus says the LORD,
Who gives the sun for a light by day,
The ordinances of the moon and the stars for a light by night,
Who disturbs the sea,
And its waves roar
(The LORD of hosts is His name):
‘If those ordinances depart
From before Me,’ says the LORD,
Then the seed of Israel shall also cease
From being a nation before Me forever.’
That the return will involve "all the house of Israel, all of it" Is EXPLICITLY stated in Ezekiel 36:1-10.
And the boundries of the land of Israel in that day are EXPLICITLY stated in Ezekiel 47:13-20.
All this, and MUCH more, is EXPLICITLY stated in Bible prophecy, contrary to your false claim that ALL Bible prophecy is stated in dark sayings and parables. SOME Bible prophecy is indeed stated that way, but MUCH of it is not.
