What does Luke 13:6 mean?
Prior lessons were Jesus speaking about people repenting to each other (Luke 12:57–59) and to God (Luke 13:1–5). He points out that the time to do so is short, but reconciliation is much better than judgment.Now, He expands the message to Jews as a people, as represented by the fig tree (Hosea 9:10; Jeremiah 8:13; 24:1–10). The owner of the tree, God the Father, sees no fruit. In fact, the tree hasn't produced fruit in the past three years. He tells the vinedresser, Jesus, to cut it down. The vinedresser begs for one more year. He will fertilize it with manure and see if it will "repent"—or turn away from—its fruitlessness. If it still doesn't, it will be cut down (Luke 13:6–9).
In Luke 12:57–59, Jesus tells the offender to reconcile with the victim. In Luke 13:1–5, He tells the sinful people to reconcile with the God they have sinned against. Here, He shows how He is trying to orchestrate reconciliation between God and the sinful nation. For now, the people will fail to hear His warning. As a nation, Jews will demand His death. As a nation, they will reject the apostles' teaching. In AD 70, the nation will be destroyed.
Jesus will compare Israel to a fig tree during Passion Week, as well. As He approaches Jerusalem, He sees a fig tree that does not produce fruit. He curses it, and it dies (Matthew 21:19–21; Mark 11:13–14, 20–21). Israel has had many opportunities to repent and recognize their Messiah (Luke 12:54–56). They choose to crucify Him instead.
