On Israel's feast of Shavuot(Pentecost), three thousand Jews received their Messiah. A couple of days later another five-thousand Jews were saved.
Yet, Peter still appeals to Israel in Acts 3 saying, that if they will repent, the GOD would send Jesus for the days of restitution of all things spoken by the prophets.
The salvation of corporate Israel cannot be separated from the promises concerning the land.
Jer 23:5 Behold, the days come, saith the LORD, that I will raise unto David a righteous Branch, and a King shall reign and prosper, and shall execute judgment and justice in the earth.
Jer 23:6 In his days Judah shall be saved, and Israel shall dwell safely: and this is his name whereby he shall be called, THE LORD OUR RIGHTEOUSNESS.
Jer 23:7 Therefore, behold, the days come, saith the LORD, that they shall no more say, The LORD liveth, which brought up the children of Israel out of the land of Egypt;
Jer 23:8 But, The LORD liveth, which brought up and which led the seed of the house of Israel out of the north country, and from all countries whither I had driven them; and they shall dwell in their own land.
Jews all over the world still celebrate their deliverance from Egypt.
There's coming a time when they will, instead, celebrate their wholeness in the land.
Jews today and for the last two-thousand years are saved the same way Gentiles are saved and become part of the body of Christ.....but there is coming a day for 'corporate' Israel.
