A man falls overboard

As this man is floating in the ocean, a boat comes and asks him if he wants to be saved, but he says "No, I am a devout Christian, God will save me." 

The guys on the boat are a bit confused, but they leave.

Another boat comes along and asks the man if he wants to be saved, but again he says to them. "No I am a devout Christian, God will save me." 

So the boat goes on its way.

The man drowns and goes to heaven, were he asks God "Why didn't you save me?"

God replies, "My son, I sent you two boats. Did you want the Titanic?"
