Saved from what? Until one comes to the realization that they need salvation they won't be able to answer this. God brought salvation through the Jews. He did it through a process where they should have concluded their deep need for a Savior. The Ten Commandments were given for this reason to reveal sin, man's moral failure, and the need for salvation. We need to be saved from ourselves!
Paul here in Romans 10 shares about the longing of his heart that Israel would be saved. It was not that they were unaware of God, they actually were zealous for Him, the issue was they were misdirected. They thought they would be saved through their own righteousness through knowledge and obedience to the law. It should have been clear to them as described in Romans 7, that the things they want to do, they don't do, and the things they don't want to do, they do. The nature of sin cannot be overcome by just knowledge of it. One can only change if their heart changes, and that is only made possible through Jesus Christ who took our sins on the cross and by His resurrection gave the gift of the Holy Spirit, the same Spirit that empowered him in his flesh to live sinless, to those who believe.
You may know people who think they are saved because they go to church, say the rosary, help those in need, but works do not save us, let us not be misdirected like the Jews, Paul was addressing. The only way we are made right with God is through faith in Jesus Christ. We must repent of all our wrongs and also of trying to be right on our own. Then as it says in verse nine "we must believe in our heart that Jesus was raised from the dead" for the forgiveness of our sins in order to be saved.
We don't need to try to convince someone they need salvation we just need to tell them and if their hearts are open they will respond. As verses 7 and 8 reveal the message is not something we need to go to heaven or to the place of the dead to confirm, no, for it is written in our hearts. God desires not just Israel but the whole world to be saved as it says in John 3:16-7. The problem some have in receiving this good news is deception. All we can do is keep presenting Truth in word and deed and believe that it will expose the lies in due time.
There is no other way to the Father but by the Son, yes, for both Jew and Gentile. Verse 15 reveals what is needed for the world to be saved? The messengers need to be sent with the message of the gospel. We are God's sent ones, His apostolic people. Our family gatherings, work environments, community events, market places, etc. are the places we are to go with the seed of the gospel, to plant, and water, trusting God to bring the harvest. Knowing not everyone will welcome the good news but for those who do, faith comes by hearing and hearing God's Word.
Israel has no excuse the messenger came with the message and they as a whole rejected their Savior. Israel represents all of mankind, no matter what people group God had chosen to bring the Savior, it would have come with the same result. The promise in Romans 11:11 is that Jews will be provoked by Gentiles by their relationship with the Lord and they will return to God and accept Jesus Christ as their Savior.
Are you saved? If you believe in your heart Jesus was raised from the dead, then yes, you are!
