This is a joke my father told us the other day:
A Rabbi lived in a remote shack, and the weather forecast said there will be a large flood. So two people arrived there in a Jeep and told the Rabbi: “Rabbi, there will be a flood, come with us so you'll be saved.” and the Rabbi said: “No, that's OK - God will save me.”.
And indeed it started to rain, and there was a lot of water, and so a boat arrived at the Rabbi's house and the people there told the Rabbi: “Rabbi, there's a flood, come with us and you'll be saved.” and the Rabbi told them: “No, that's OK - God will save me.” and he remained there.
And it continued to rain, and the water level went up and the Rabbi had to climb to the roof of his shack. A helicopter arrived at his shack, and the people inside told the Rabbi: “Rabbi, there's a big flood. Come with us to safety.”, and the Rabbi said: “No, that's OK - God will save me.”. And the Helicopter left.
The water levels rose even more, and the Rabbi drowned, and his soul went to heaven. There he confronted God and asked him: “Dear God, why didn't you save me?”, and God replied “Well, I tried. I sent you a Jeep, a boat - even a helicopter - but you wouldn't accept any of them. What more could I have done?”
The moral of this story is: God helps them that help God help them.
