Do you think that someone who follows rabbinical Judaism can be justified by God apart from Christ?
A person has only one way to come to G-d, through grace. Grace is G-d's movement towards man.
In the past, He scattered them, but now He is gathering them. In days gone by, He made them a proverb, but now they shall be a praise upon the earth.
as ye were a curse among the heathen, O house of Judah, and house of Israel; so will I save you, and ye shall be a blessing: fear not, but let your hands be strong. Zec 8:13b
The restoration of Israel must be understood as a process that develops over time. It begins with a physical restoration in their land. Then follows spiritual restoration.
Most of these same prophets proclaim that G-d will pour out His Spirit on the people of Israel. They foresaw that He would give them a new heart and write His law on their hearts. This will be so radical that Paul describes it as being brought back to life. The blindness that Paul sees both in the nations (2 Corinthians 4:3ff) and in Israel (2 Corinthians 3:14ff) will finally be removed from humanity
And he will destroy in this mountain the face of the covering cast over all people, and the vail that is spread over all nations. Isa 25:7
Isn't it true that the congregation has lost much? Such as the Torah, for example. Our forefathers called the Torah a foreign teaching (Hosea 8:10). And the Jewish people have lost the Messiah. Both must be found and brought back. The Torah must be brought back to the lost sheep of the house of Israel in the nations (the ten lost tribes, the house of Jacob) and the Messiah to the tribe of Judah, the Jews
Thus saith the Lord, Stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk therein, and ye shall find rest for your souls. But they said, We will not walk therein. Jer 6:16
If you take the word for congregation in the Torah, it is the same word in a Hebrew translation of the NT. Unfortunately, the translators never rendered it that way, which could give the impression that the congregation (church) is something different from the congregation in the Torah. From YHVH's perspective, there is only one congregation, one law (Torah), one king and one country. This also applies to strangers. The Torah repeatedly states
One law shall be to him that is homeborn, and unto the stranger that sojourneth among you. Ex 12:49
YHVH presents a covenant to all (the two houses and the strangers). Whoever enters into the covenant and keeps the terms of the covenant belongs to the bride.
This spiritual restoration of Israel will lead to the time of messianic rule on earth. The prophets saw the day coming when
‘the Branch of righteousness to grow up unto David’ who will rule over his people. Jesus himself proclaimed that Israel would not see Him again until it welcomed Him back into the city. Both the Hebrew prophets and the apostle John see Israel at that time ‘
look upon me whom they have pierced,’ (Zec 12:10; Rev 1:7).
But the greatest promise is that the restoration of Israel will lead to the defeat of the power of death
He will swallow up death in victory; and the Lord God will wipe away tears from off all faces; Isa 25:8a
Paul refers to this when he speaks of the resurrection from the dead (1 Cor 15:54). This means that Israel's restoration will finally put an end to mankind's greatest fear to this day, the fear of death. Its poisonous sting will be broken, and death will not have the last word; rather, this will belong to the resurrection life of Jesus Christ.
That is why Paul could triumphantly proclaim about Israel:
For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead? Rom 11:15
This means that Israel's greatest calling still lies ahead of us. We must recognise that G-d is restoring His people to their inheritance, their relationship with Him, and their destiny.
