Romans 11:18

You do not support the root, but the root supports you: When Paul wrote to the church in Rome, most of its members were not Jewish. This was common in many early Christian communities.

Because Gentiles had become the majority, some began to boast about their place in God’s people. Some also looked down on Jews and on Israel’s religious heritage. Paul corrects this attitude. He reminds Gentile believers that they share in God’s blessings only because they have been joined to God’s people. That people is rooted in God’s promises to Israel.

In Paul’s extended metaphor, God’s special olive tree represents the people of God. This image would have been familiar to his readers. The olive tree was the most common fruit tree in the Mediterranean region. It was also already used as a symbol for Israel in the Old Testament (Jeremiah 11:16; Hosea 14:5–6).

Paul describes non-Jewish (gentile) Christians as branches from a wild olive tree because they were not originally part of God's people.

n this section, Paul addresses a serious question. Many Jews did not believe in Jesus. If God had promised salvation to Israel, how could Jesus truly fulfill God’s plan when so few Jews believed (9:1–5)? In response, Paul uses the Old Testament to show that God always planned to save only a remnant, that is, a smaller group within Israel (9:6–29). Paul also explains that many Jews did not accept Christ because they refused to trust in him (9:30–10:21).

Paul then makes clear that God has not rejected Israel. Some Jews have already believed in Christ (11:1–10). Many more will trust in Christ in the future (11:12–26).
