Amos 8 is pretty clear that he was done with nation of Israel forever in Amos. How do you reconcile that?
Let's see if that is the whole story . . .
Jeremiah 31:35-37 KJV
35) Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts is his name:
36) If those ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever.
37) Thus saith the LORD; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the LORD.
And Amos echoes this intent of God's,
Amos 9:14-15 KJV
14) And I will bring again the captivity of my people of Israel, and they shall build the waste cities, and inhabit them; and they shall plant vineyards, and drink the wine thereof; they shall also make gardens, and eat the fruit of them.
15) And I will plant them upon their land, and they shall no more be pulled up out of their land which I have given them, saith the LORD thy God.
Much like Ezekiel,
Ezekiel 39:27-29 KJV
27) When I have brought them again from the people, and gathered them out of their enemies' lands, and am sanctified in them in the sight of many nations;
28) Then shall they know that I am the LORD their God, which caused them to be led into captivity among the heathen: but I have gathered them unto their own land, and have left none of them any more there.
29) Neither will I hide my face any more from them: for I have poured out my spirit upon the house of Israel, saith the Lord GOD.
And more . . . Jesus also prophesied that Israel would remain, and be rescued, and be saved in that day.
Much love!
