I tried to find a Yiu-Tube clip for this but failed - so I will describe the scene.
It comes from my favourite Burt Reynolds movie "The End". Burt's character has a terminal illness and has spent the movie trying to end it all so he does not suffer horribly. Fun plot, huh? Finally he decides to swim out to sea and drown, so off he goes, swimming until he is exhausted, then he dives under...
He resurfaces, shouting "I want to live!" and sets off for the shore again.
As he goes he starts trying to strike a deal with God, saying he will stop doing all the bad things he has been doing all of his life and saying he will donate 90% of his money to the Church, etc.
Then he realises that he is getting closer to the beach and starts thinking he might make it, so he starts knocking down his offer - 50%, 25% gross, 10%, 10% starting in 5 years. As he staggers up the beach he is blaming God for making him sick in the first place!
Do you see where I am going with this? Of course you do!
And we don't just do this to our own particular God either! We do it to our friends who help us out in the bad times - do we really remember and show our gratitude when things are better? I like to think that I do, but the more I think about it the less certain I become!
As I said: something to ponder...
