There is a nice little story to that:
A man is trapped on a lonely island. Every day he prays for God to help him. After a few weeks, a ship arrives at the island. But the man says "Leave me here! God will come and save me."
So the ship leaven and the man stays on the island. And again he prays everyday to be rescued.
After another couple of weeks a second ship finds the man. But again he insists on staying, knowing that god will come and rescue him.
Another week passes and the man is getting really sick. He has no food left and is close to his death. With his last breath he asks:
"God, why didn't you come for me?"
And God answeres:
"I sent you two boats. What else did you expect me to do?"
