Some students of the Bible understand Romans 9 to teach that God sovereignly chooses some people to go to Heaven and some to go to Hell. However, this understanding ignores the argument of the book of Romans and the context of Romans 9.
The book of Romans is dealing with salvation from the present-day wrath of God which involves God giving the unrighteous over to the downward spiral of the degradation of sin (Rom. 1:16-32). Because God is holy and hates sin, we must first be delivered from His wrath toward sin through justification which is by faith alone in Christ’s death (Rom. 2:1-5:10a). We can then experience deliverance from God’s present-day wrath and the perversion of sin through faith in Christ’s life (Rom. 5:9-8:39).
The argument of Romans up to the end of chapter 8 is a direct challenge to the commonly held belief of first-century Jews that because they were God’s chosen people they would be saved from hell simply by being of Jewish descent and by keeping the Law (cf. Rom. 2:17-3:20). This assumption, says Paul, is absolutely false. The problem is that the Jews were confusing election to service with election to salvation (cf. examples of election to service: Jeremiah – Jeremiah 1:5; Paul – Gal. 1:15-16; John the Baptist – Luke 1:13-17; John 1:23; the disciples (John 15:16). They assumed that because God chose them as the means by which “all the families of the earth will be blessed” (Gen. 12:3), He also chose them, simply as Jews, for salvation. But now they hear Paul saying, “No! Jews do not have a unique path to heaven; on Judgment Day they will be treated like everyone else.” So now they are thinking, “That’s not fair! God has just been leading us on, giving us promises He never meant to keep. He is going back on His word! Where is the justice?”
So in Romans 9 Paul is defending God’s righteousness in His dealings with the Jews and the Gentiles. The Word of God has not failed (Rom. 9:6a). When God says that only those Jews will be saved who trust God’s promises, like their father Abraham did, He is not breaking His original promises to Israel. His choice of the nation as a whole was not a guarantee of any individual Jew’s salvation. God graciously and sovereignly chose Israel to be the nation from which “Christ came, who is over all, the eternally blessed God” (Rom. 9:5). God’s choice of the nation of Israel to bring the Messiah-God into the world was not based upon their natural descent or works (Rom. 9:6-11), but upon His merciful and sovereign choice (Rom. 9:11b-16). And God certainly has the sovereign right to use any individual or group that He chooses for such a purpose, without any promise of personal salvation from Hell being attached.
An example of God choosing someone for service without providing individual salvation from Hell for him is Pharaoh (Rom. 9:17; cf. Judas whom Jesus chose to bear fruit in ministry even though Judas never believed in Jesus – John 6:64; 13:10-11; 15:16; 17:12). God both “had mercy” on Pharaoh by choosing him for an important role in birthing the nation of Israel, and He also “hardened” him in order to accomplish the same purpose (Rom. 9:18). An example of a nation being chosen for service and not salvation is Israel at this present time (Rom. 9:31-10:4). The nation of Israel rejected Jesus as their Messiah which led God to show mercy to Gentiles by including them in the church. An elect person or nation is never guaranteed justification. In the Old Testament, God chose the nation of Babylon to discipline Israel (see Habakkuk). Likewise, He chose King Cyrus of Persia to help Israel and to subdue the nations (Cyrus is even called God’s “shepherd” and “anointed” in Isaiah 44:28 and 45:1). But neither of these sovereign choices proves anything regarding individual or corporate salvation from Hell.
If God chooses individuals and nations to service based upon His merciful and sovereign will, and not human behavior, “Why does He still find fault?” Paul’s listeners would ask him (Rom. 9:19). Paul responds by saying that people are not in a position to criticize their Judge because He is the standard by which we measure justice (Rom. 9:20-30).
God chose the nation of Israel to service and blessings for the purpose of sharing those blessings with others. But since they failed (Rom. 9:31-11:10), God saw fit to elect another group called the Church (composed largely of Gentiles) to accomplish this task (Rom. 11:11-25). Fortunately for Israel, because God is gracious He will again return to them and fulfill His promises and plans (Rom. 11:23-32). How unsearchable is God and His ways (Rom 11:33-36)!?
Conclusion: God’s election relates to His merciful and sovereign choice to choose individuals and/or nations for service (not salvation), especially as it relates to sharing His blessings with others, including the gospel. Just as the nation of Israel was chosen by God to bring the Messiah-God into the world (Rom. 9:5) and be a channel of blessing to all families/nations (Gen. 12:3), so believers (both Jews and Gentiles) in Christ today, are sovereignly chosen by God to be His mouthpieces of blessing to others (cf. Luke 6:13; John 15:16; Acts 1:2, 8; 9:15; 10:41; 15:7; 22:14-15; 26:16-18; James 2:5; I Pet. 2:9).
