The nation that will bring forth fruits is the current nation of Israel, when they become Christians in the middle of the seven years.
Obviously you did not read Scripture well. Let start over.
Matthew 21:42-43 KJV
[42] Jesus saith unto them,
Did ye never read in the scriptures, The stone which the
builders rejected, the same is become the head of the corner: this is the Lord's doing, and it is marvellous in our eyes?
[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.
It is the builders of the old testament congregation who have rejected and put Christ to death, right? How? Now Consider wisely:
John 2:18-21 KJV
[18] Then answered
the Jews and said unto him, What sign shewest thou unto us, seeing that thou doest these things?
[19] Jesus answered and
said unto them,
Destroy this temple, and
in three days I will raise it up.
[20] Then said the Jews, Forty and six years was this temple in building, and wilt thou rear it up in three days?
[21]
But he spake of the temple of his body.
See, it was the builders, the "people of the prince" that come and destroy temple, Daniel 9:26. And pay attention to this, in
THREE DAYS, Christ rise it up along with his resurrection. His body NOW represents the new Testament congregation where Christians, as bulders, of that temple! This is the holy nation that Christ gave the kingdom of God to! Speaking to Church, Peter wrote:
1 Peter 2:9 KJV
[9] But
ye are a chosen generation, a royal priesthood,
an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
This is holy nation, the New Testament Congregation, that Christ rebuilt with Christians therein! Just like Jews were with their old testament congregation.
BOTH represented the temple of the body of Christ! The first one was destroyed by Old Testament builders. The second one was rebuilt with New Testament builders. yet one and same Congregation of Israel because it is Christ's body! This is how Christ has removed the kingdom representatives from old to the new. The Jews in the New Testament will have gospel to become saved. That is why Christ said blindness in PART is happening to Israel (Jews) because there are few who will be saved by hearing the Gospel during the New Testament. This is why we have a great commission to bring fruits to Christ's church! Not nation Israel fantasy of yours! There will be no "national salvation" for the Jews in the end like you believe! Sorry!
Listen, Christ said the temple rebuild in
three days. This is was the
rebuilt temple Christ gave His Kingdom representative to! Not to the Jewish nation some two thousand years later! Modern Israel does not qualify! She did not exist three days after the death of Christ. Please stick with Gospel, not Youtube, Jack Van Impe or Josephus!
