We all know that people are saved under the new covenant, right? Now notice the wording of this new covenant: “Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah” (Jeremiah 31:31).

And in the book of Hebrews, Paul expands on this concept: “Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah. ... For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people: And they shall not teach every man his neighbor, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest. For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more” (Hebrews 8:8, 10–12).

The new covenant is made “with the house of Israel”!
God never makes a salvation covenant with Gentiles. In fact, nowhere in Scripture do you find any saving covenant made with anyone but Israelites! So if you want to be saved, you must be born again as a spiritual Jew. This is not to say that all Christians must now be circumcised and sacrifice lambs, but we must have the spiritual equivalent of these things—Jesus, the Lamb of God (the final sacrifice), and circumcision of the heart.

God does not have one method of salvation for Jews and a different one for non-Jews. Everyone is saved the same way under the same program—by grace through faith. Paul uses the analogy of an olive tree to explain that all Gentiles who are saved are grafted into the stock of Israel. “And if some of the branches be broken off, and thou, being a wild olive tree, wert grafted in among them, and with them partakest of the root and fatness of the olive tree; Boast not against the branches. But if thou boast, thou bearest not the root, but the root [supports] thee” (Romans 11:17, 18).

The Christian religion is based on a Jewish manual called the Bible. (In this light, it is difficult to understand how any professed Christian could be anti-Semitic.) Christianity is not a new religion, but rather the completion of the Jewish faith. So with this in mind, we can now better understand what Paul meant when he said, “And so all Israel shall be saved” (Romans 11:26). Some take this verse to mean that God will ultimately save all literal Jews. If this were true, it would contradict every principle of God’s dealings with humans throughout history and Scripture. God is not a racist. In Jesus’ eyes, “There is neither Jew nor Greek” (Galatians 3:28).

We are saved based on choices we make regarding God’s provision, not on national status or physical citizenship. But if, when Paul says that “all Israel will be saved,” he is speaking of spiritual Israel, and if we understand that we become a “true Jew” only by a choice, then it all makes sense.
