What does Luke 13:30 mean?
Jesus finishes His explanation that neither prestige nor ancestry nor ability are necessary for salvation. All that matters is repentance and faith in Christ. Because of that, the time to reconcile with God is limited. Many Jews will not spend eternity with God while many Gentiles will (Luke 13:1–9, 22–29).The concept of the last becoming first and first becoming last appears in a few different ways. Here, Jesus is talking about how Gentiles from all over the earth will live in the kingdom of God for eternity while many Jews will not. The Jews were the "first" in that they are meant to be God's people, physical heirs of Abraham to whom God gave His covenant (Luke 13:28).
The reason God chose the Jews was to show the Gentiles who God is and what He expects (Exodus 19:6; Joshua 22:5; Jeremiah 13:11). In Old Testament terms, they disqualify themselves from remaining in the kingdom through disobedience (Amos 3:2). When the Jewish leadership crucifies Jesus instead of worshiping Him, they prove themselves ineligible to spread God's message of salvation.
Jesus uses a parable to explain this. "Workers of evil" will not be allowed in the kingdom even if they are physically descended from Abraham. Identification with Jesus and repentance from sins leads to an invitation to stay with God for eternity (Luke 13:5, 25–29). As Paul will later write, "And if you are Christ's, then you are Abraham's offspring, heirs according to promise" (Galatians 3:29).
In the church age where identification with Jesus brings salvation, the Gentiles—the last to know God—will be first to accept Christ. But "first" and "last" affirm that Jews as a nation still have hope. Romans 11 explains that the Jews will accept Jesus as their Messiah and will do so naturally. The salvation of Gentiles reconciles the world to God, but it will also make the Jews jealous so they will want to return to Him.
Jesus uses this phrase in a similar way in the parable of the laborers in the vineyard (Matthew 20:16). The other way in which Jesus uses this proverb is when He tells His disciples to live and work in humility, service, and sacrifice, trusting that God will reward them (Matthew 19:30; Mark 9:35; 10:31).
