In Luke 13:1-9 Jesus first discusses two disasters: Pilate's killing of Galilean worshippers and a falling tower that killed eighteen people. Jesus then adds a parable about a barren fig tree that's given one more opportunity to bear fruit. His teaching contains these four lessons:
1. Disaster victims are no better or worse than others (v1-5).
2. Everyone must either repent or perish (v3,5).
3. God demands fruitfulness (v6-7).
4. God is patient, but only for a limited time (v8-9).
