'Will Be Saved' in the Bible
Therefore, by much more, [because we] have been declared righteous now by his blood, we will be saved through him from the wrath.
For if, [while we] were enemies, we were reconciled to God through the death of his Son, by much more, having been reconciled, we will be saved by his life.
And Isaiah calls out concerning Israel: “Though the number of the sons of Israel be like the sand of the sea, it is only the remnant [a small believing minority] that will be saved [from God’s judgment];
because if you acknowledge and confess with your mouth that Jesus is Lord [recognizing His power, authority, and majesty as God], and believe in your heart that God raised Him from the dead, you will be saved.
For “whoever calls on the name of the Lord [in prayer] will be saved.”
Now if the Jews sinning meant blessings for [the rest of] the world, and their [spiritual] defection meant blessings for the Gentiles, how much more will their fullness [also produce blessings]! [Note: "Fullness" here may mean either a large or the complete number of Jews who will be saved, or become completely obedient to God].
For I want you to know this secret, brothers, so you will not become conceited: Part of the Israelites have become [spiritually] insensitive [to God], [and will remain that way] until the fullness of the Gentiles occurs. [Note: As with verse 12, concerning the Jews, "fullness" here may mean either a large or the complete number of Gentiles who will be saved].
and so [at that time] all Israel [that is, all Jews who have a personal faith in Jesus as Messiah] will be saved; just as it is written [in Scripture],“The Deliverer (Messiah) will come from Zion,He will remove ungodliness from Jacob.”
