You are both wrong.
The Gospel went to the "house of Israel", the ten scattered tribes, long, long ago, with the establishing of the Western Christian nations which fulfilled Ephraim's seed becoming "a multitude of nations" (Genesis 48). Lord Jesus in Matthew 21 even pointed to the "house of Israel" when He gave the "vineyard" parable, because Isaiah 5 is where He declared the ten tribe "house of Israel" as the 'vineyard' and Judah as His 'pleasant plant'.
The ten tribe "house of Israel" with believing Gentiles came under the New Covenant in Christ Jesus. And the ten tribe "house of Israel" originally made up the MAJORITY of Israelites. Thus Apostle Paul calls Christ's Church "the commonwealth of Israel" in Ephesians 2. Only a small remnant of the "house of Judah" (JEWS) converted to Jesus Christ.
God's Israel = Christ's Church
Speculation. Your understanding on "the lost tribes of Israel" is biblically lacking.
Allow me to explain WITH SCRIPTURE regarding the so-called ten lost tribes of Israel. Why is it important to know what happened to the 10 northern tribes of Israel? Well, there are many reasons, not the least of which is that the lost tribes of Israel prefigures the lost sheep of Israel, who when Jesus Christ (the greater Cyrus) would come, would seek and return them to the restored kingdom, fulfilling the prophesy of the throne of David.
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?"
They were asking Jesus when Israel would again become a restored Kingdom. Unlike man today, they understood the literal Israel was not lost. And Indeed Christ had promised the 12 Apostles that they would sit judging the 12 tribes of Israel
in the regeneration. They could hardly sit judging these tribes of Israel, if the 12 tribes were lost or not accounted for. Selah!
Matthew 19:28
- "And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel."
It is pretty clear Jesus is declaring that when He sits to rule on the throne of His Glory, the apostles would also sit as Kings and priests unto God to rule. And Christ clearly identifies the time of His sitting to rule in His Glory as, "
in the regeneration." The question then is, biblically speaking, when is the regeneration? ..when does Christ reign in His Glory?
Titus 3:5
- "Not by works of righteousness which we have done, but according to his mercy he Saved us, by the washing of regeneration, and renewing of the Holy Ghost;"
John 17:4-5
- "I have glorified thee on the earth: I have finished the work which thou gavest me to do.
- And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was."
1st Corinthians 15:25
- "For he must reign, till he hath put all enemies under his feet."
This is when
"the regeneration" occurs, according to God. What is the Regeneration? This is the Greek word [
paliggenesia] taken from the root words [
palin] meaning again or repeat, and [
genesis] meaning a birth or nativity. In other words, to be born again.
A spiritual nativity where they are made new by the Holy ghost. This is 'when' these apostles would reign as they sit on thrones in Christ to rule Israel. It is in this regeneration, or after being born again from the dead, that they would reign with Him. Did they become kings and Priests unto God to sit and rule with Him when they were raised up with Christ by the Holy Ghost? The answer (according to scripture) is obvious.
Ephesians 2:6
- "And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:"
When the apostles were regenerated, born again from above, they were raised up in Christ to sit and rule with Him on His throne in heaven. When Jesus Christ ascended to the throne of David to rule the kingdom, this fulfilled the prophesy of the restoration of the Kingdom of David, and Christ sitting on that throne of Glory. As is clearly illustrated also in Acts:
Acts 2:29-31
- "Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day.
- Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne;
- He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption."
The Prophesy did not speak of an earthly reign on the throne of David, but spoke of the resurrection of Christ to sit in on His throne in heaven, and the apostles as being raised up with Him to also sit in heavenly places. The gathering of 'the remnant' of the tribes of Israel. The Old Testament restoring of the twelve tribes to the land of their fathers was the
"type" not the "anti-type," and
Cyrus fulfilled this. The Restoration of the Kingdom of God which the Apostles asked about, was accomplished in Christ being the seed of David who reconciled the dispersed to God in one body, "one Israel," one stick, united by the Lion of the tribe of Judah.
This was accomplished by His death, resurrection, and ascension to the throne. The regeneration has the 12 sit to rule with Christ. And this anti-type of the preceding type is made clear in such verses as Matthew chapter 15:
Matthew 15:24
- "But he answered and said, I am not sent but unto the lost sheep of the house of Israel."
A very open testimony to the fulfillment of scripture in this Messiah, that He came to fulfill the prophesy of restoring the Kingdom of Israel. Not in literal Israelites lost in some foreign land, but
a Spiritual Israel lost and being brought home. This is what the lost northern tribes
merely prefigured. Some of them 'cut off,' but a remnant returning. This also seen in the angel speaking to Mary of His purpose and His reign.
Luke 1:31-33
- "And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS.
- He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David:
- And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end."
Just as Acts 2 said that this prophesy spake of the resurrection of Christ ascending into Heaven to sit on the throne of David. And note, the reign is not a 1000-year earthly reign, but was prophesied to be a reign that
lasts forever over the house of Jacob. Only a reign in spiritual regeneration, Glory unto the throne of God, qualifies. This is the 'only' kingdom of which there shall be no end. The fulfillment of the prophecy of the restoration of Israel.
One may ask why the tribes are so important? It is because without knowledge of who they were, and how some were cut off while others returning (a remnant only), and of how the Temple is built again, and how the nation is restored as one people, etc., etc. We do not really understand the anti-type in Christ where the lost sheep of the house of Israel (a remnant only) return, the Temple is rebuilt in Him, and God's true Kingdom restored.
SPIRITUALLY!!!
