I just finished a book by this title written by Dean Koontz. In the book a character asks the question "What will you find behind the door that is one door away from Heaven?" Every person that was asked this question had an answer, but only one got it right the first time asked. I'm not sure there is one right answer to this question. It may be that different people would find different things. I'm not sure what my answer would be, but I love the answer given by Leilani: "If your heart is closed, then you will find behind that door nothing to light your way. But if your heart is open, you will find behind that door people, who like you, are searching, and you will find the right door together with them. None of us can ever save himself; we are the instruments of one another's salvation, and only by the hope we give to others do we lift ourselves out of the darkness into the light."
We need people to walk this journey called life with us. To walk the journey alone is to live in darkness. We need to live our life in a manner that gives others hope. Without hope life becomes, I think, meaningless and very dark indeed.
