So, you are claiming that the gentile nations will take their "inheritance", the "kingdom prepared" for them "since the creation of the world"?LOL, everyone is entitled to their opinion. I suppose you lean toward the UR or I wouldn't be receiving this post.
In answer to the meaning of your Scripture verses in Matt. 25:31-46, if you read the context, you will see that Christ is addressing the Gentile nations, in other words, this is "the judgment of the nations.
This takes place at the Second Coming, as plainly seen in 25:31. Christ is judging the Gentile nations according to how they treated Israel in the "time of Jacob's Trouble." The Second Coming takes place as the anti-christ is destroying Israel, The Warrior King that Israel looked for at His first coming is now revealed. Christ saves Israel, this is the moment that Paul speaks of "and all of Israel will be saved."
The nations that Christ referred to as "I was hungry and you gave me no meat, thirsty and you gave me no drink," are the nations that did not help Israel, but joined with the anti-christ to destroy them.
Sounds like UR to me. - LOL
Matthew 25:34 NIV
“Then the King will say to those on his right, ‘Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world.
