My family went on a transatlantic cruise trip back when Iceland started spewing and messing up everyone's flights. Two problems: We disembarked in Barcelona and hoped to go to Poland to visit some relatives but no such flight from Barcelona to the city in Poland existed. Second problem: once we wanted to go back to America, we wouldn't be able to since the volcanoes shut down flights for weeks. What ended up happening was an obscure airline opened up nonstop flights from Barcelona to the city in Poland that started on the day we disembarked and the day that we booked our flights to return to America, all of the volcano stuff disappeared for that one day. My point is, those would be crazy to say that they're both coincidences and not acts of God but because you cannot provide any evidence that God influenced it you have to call them coincidences or "luck".
