27 Isaiah also cries out concerning Israel: “Though the number of the children of Israel be as the sand of the sea, The remnant will be saved. 28 For He will finish the work and cut it short in righteousness, Because the Lord will make a short work upon the earth.” 29 And as Isaiah said before: “Unless the Lord of Sabaoth had left us a seed, We would have become like Sodom, And we would have been made like Gomorrah.”
Verses 27 to 29 are about calling out a remnant from Israel of true believers. Most of the Jews of Paul’s day did not believe that Jesus was the Messiah. Paul continued his argument from Isaiah.
Isaiah also cries [passionately] out concerning Israel:
Paul quoted Isaiah 10:22-23 and 1:9 to show that there will be a remnant of Israel who will come to Messiah Jesus. Isaiah prophesied about 760 B.C. to the southern kingdom of Judah for 48 years. He also, like Hosea, prophesied that Israel would undergo divine discipline. Judah’s rejection of God resulted in exile to Babylon by king Sennacherib. This was a preview of the Israel of Paul’s day rejecting the Messiah.
“Though the number of the children of Israel be as the sand of the sea, The remnant will be saved.
Only a minority of the vast numbers of Israel will accept the Messiah. God will restore this group to a national entity in the Millennium. Salvation here is not regeneration but restoration of believing Israel to her land. Those Jews restored to the land will be strictly regenerate.
Verse 28 is the basis for verse 27 and is a reference to Isaiah 10:22-23.
He will finish the work and cut it short in righteousness,
God will decisively dispense salvation for the remnant. The Lord Jesus will execute His Word at the Second Advent. The 490 years of divine discipline on Israel (including the 7 years of Tribulation) come to an end. At that time the Millennium will begin.
Because the Lord will make a short work upon the earth.”
God executed judgment of Judah through the Babylonians, but He cut it short by saving a remnant. Unless God had left a remnant, Israel would have been wiped out as a nation.
In the future God will save a remnant out of the Tribulation. The majority of Jews will have been slain during the Tribulation. God will make short work of the Tribulation period. This period will close both the times of the Gentiles but also the protracted period of divine discipline upon Israel.
And as Isaiah said before:
This verse is a quotation from Isaiah 1:9 whereby Paul shows that, if it were not for the remnant, Israel would had been cut off completely.
“Unless the Lord of Sabaoth [armies] had left us a seed [the remnant],
Unless God had intervened, even the remnant would not have been saved. The “LORD of Sabaoth” is the Lord of Armies. The Lord Jesus is a mighty warrior. At the Second Coming, if not for His sparing by grace the remnant who embraced Him as Messiah, He would completely wipe out Israel.
We would have become like Sodom, And we would have been made like Gomorrah.”
Israel was no better than Sodom and Gomorrah, which God wiped out because of sexual perversion. These cities were the epitome of evil and experienced swift judgment. Israel did not deserve salvation but had to depend on the grace and mercy of God for salvation. God tempered His judgment and saved the regenerate remnant because of His grace.
The Lord so decisively cut Israel off that the remnant appeared like a greatly reduced entity of the nation. Yet no matter how small the remnant might be, there will be a great restoration in the latter days.
God is completely faithful to His system of salvation by grace to Israel.
God’s plan of salvation continues in a remnant. He is always consistent in His plan of salvation by grace. Natural Israel rejected this system of grace, so God turned to a remnant. His salvation is always by grace whether in the New or Old Testament. He will never change the nature of salvation, even though few believe it.
