Genesis 12:1 Now the LORD had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will shew thee:
2 And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:
3 And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.
Here is what the text states-----And I will make of thee a great nation
Whatever nation that was meaning back then in Abraham's day, it would have to still be meaning this same nation today.
Matthew 21:43 Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof.
Here's the problem. If the nation the kingdom of God shall be taken from is meaning the same nation God said He would make a great nation per Genesis 12:2, and is given to a different nation, that nation it is given to can't be meaning this same nation in Genesis 12:2 then. Because if that nation was really meaning the nation in Genesis 12:2 the kingdom of God is given to per Matthew 21:43, how does one explain it gets taken away from others already in possesion of the kingdom of God, then given to a nation that had not already been in possession?
Acts 1:6 When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?
7 And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.
Wonder why they asked this? Maybe because of Matthew 21:43 for one. And the fact Jesus never told them they were wrong to even think such a thing, obviously then, Matthew 21:43 wasn't meaning for forever when it stated---Therefore say I unto you, The kingdom of God shall be taken from you.
