You are telling a story not explaining science or mathematics.  So no need to have all these superfluous detailed explanations.  The readers can infer.

GOD's ways to help you ( a little bit look like a Joke) You need to capitalize all words in a title.

Mysterious Ways of God A catchier title.  Titles should be concise, short and interesting.

One day there was A person was stranded in on an island.. He had not been eaten for awhile. 1 long time.. However, he really.. really believed in God.  GOD..
One time there was a boat through near that island and then some conversations happen...

Then a boat came...

the Sailor: "Hey man! What are you doing there?.."
Stranded person: "I'm stranded! here.."
Sailor said : "Ok!.. come with me i will help you go home Hop on over!"....
Stranded person: "No thanks... I don’t need your help!.. because GOD God will help me!.."
Sailor: "Suit yourself!"oh.. ok i will go then..

[A day later...]

* there was Another sailor through near that came by the island... and same condition happen again... Again he refused to get on board the boat because he believed that God will help him.  Finally no more boats came and the man died from starvation.

On meeting God, he asked,

"O Lord, I truely believe in thee.  Why didn't you help me on the Island?"

"Of course I did!  I sent two boats but you refused my help!"

the Sailor: "Hey man what are you doing there.."
stranded person : "i'm stranded here.."
sailor said : "ok.. come with me i will help you go home"....
Stranded person : "No thanks, i dont need your help.. cuz GOD will help me.."
Sailor : oh ok i will go then..

[a day later : no more sailor or anyone through this island there was no one who would help him until he passed away ]

on next time he met GOD.. and there were some conversations :

stranded person : “Oh GOD i really believe in you.. why don’t you help me until i died”..
GOD : “I have helped you by sending two boats.. why don't you understand...?”

A period is just one dot.  Not two.  You are overusing the ellipsis the 3 dots together.  Similar to a story I wrote... http://www.italki.com/notebook/entry/103998.htm

1.  A person will be having serious problems if he does not eat after a week.  "A while" denotes a shorter time.  I prefer to write "and he was hungry".
