Romans 9-11 is not Scripture proving that God called certain people.
That's exactly what it is. Romans 9-11 is about God calling His people Israel, His elect. He has mercy on whom He will, compassion on whom He will (Paul, quoting Moses, who quotes God in Exodus 33:18, in Romans 9:15, and restating it emphatically in Romans 9:18). And God's elect, while people of every tongue, tribe and nation ~Jew and Gentile, as it were ~ are a subset of all people. In Romans 10, Paul refers directly to Joel's quote of God in 2:32 in saying, "everyone who calls on the name of the Lord will be saved," and if you read Joel 2, you should quickly see that this 'everyone' is only those whom the LORD calls" ~
"And it shall come to pass that everyone who calls on the name of the LORD shall be saved. For in Mount Zion and in Jerusalem there shall be those who escape, as the LORD has said, and among the survivors shall be those whom the LORD calls." And finally, in Romans 11, Paul says,
"So too at the present time there is a remnant, chosen by grace..." (v.5) And keeping in mind that God has mercy/compassion on whom He wills and hardens whom He will, Paul states clearly that
"a partial hardening has come upon Israel, until the fullness of the Gentiles has come in... (a)nd in this way all Israel will be saved." (vv.25-26)
Don't you see how corrupt this becomes when we do not follow to whom it is addressed?
And to whom do you believe it is addressed, Peterlag? This is a personal letter written by Paul to the Christians in Rome, hence the title of the epistle, Romans. And of course he says the same things in different ways to the Ephesians, the Colossians, the Thessalonians, etc.
And what verses are you talking about in Ephesians 1-2 and Peter 1?
In particular the bolded, emphasized here:
"Blessed be the God and Father of our Lord Jesus Christ, Who has blessed us in Christ with every spiritual blessing in the heavenly places, even as He chose us in him before the foundation of the world, that we should be holy and blameless before Him. In love He predestined us for adoption to himself as sons through Jesus Christ, according to the purpose of His will, to the praise of His glorious grace, with which He has blessed us in the Beloved. In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace, which He lavished upon us, in all wisdom and insight making known to us the mystery of His will, according to His purpose, which He set forth in Christ as a plan for the fullness of time, to unite all things in Him, things in heaven and things on earth.
In Him we have obtained an inheritance, having been predestined according to the purpose of Him who works all things according to the counsel of His will, so that we who were the first to hope in Christ might be to the praise of his glory. In Him you also, when you heard the word of truth, the gospel of your salvation, and believed in Him, were sealed with the promised Holy Spirit, Who is the guarantee of our inheritance until we acquire possession of it, to the praise of His glory."
[Ephesians 1:3-14]
*********************************************************
"And you were dead in the trespasses and sins in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience ~ among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ ~ by grace you have been saved ~ and raised us up with Him and seated us with Him in the heavenly places in Christ Jesus, so that in the coming ages He might show the immeasurable riches of His grace in kindness toward us in Christ Jesus. For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
Therefore remember that at one time you Gentiles in the flesh, called 'the uncircumcision' by what is called the circumcision, which is made in the flesh by hands ~ remember that you were at that time separated from Christ, alienated from the commonwealth of Israel and strangers to the covenants of promise, having no hope and without God in the world. But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. For He Himself is our peace, Who has made us both one and has broken down in His flesh the dividing wall of hostility by abolishing the law of commandments expressed in ordinances, that He might create in Himself one new man in place of the two, so making peace, and might reconcile us both to God in one body through the cross, thereby killing the hostility. And He came and preached peace to you who were far off and peace to those who were near. For through Him we both have access in one Spirit to the Father. So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus Himself being the cornerstone, in Whom the whole structure, being joined together, grows into a holy temple in the Lord. In Him you also are being built together into a dwelling place for God by the Spirit."
[Ephesians 2 in its entirety]
*********************************************************
"Blessed be the God and Father of our Lord Jesus Christ! According to His great mercy, He has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, who by God’s power are being guarded through faith for a salvation ready to be revealed in the last time. In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, so that the tested genuineness of your faith ~ more precious than gold that perishes though it is tested by fire ~ may be found to result in praise and glory and honor at the revelation of Jesus Christ. Though you have not seen Him, you love Him. Though you do not now see Him, you believe in Him and rejoice with joy that is inexpressible and filled with glory, obtaining the outcome of your faith, the salvation of your souls."
[1 Peter 1:3-9]
Grace and peace to you.
