This book is fiction. While there is no intention to teach anything about a special privilege to a few people in eternity as being true, the idea is to help people begin to look closely at the life they are living.
Are you driven by a passion that people will identify when they come to know you?
Are you truly a person that knows they have a purpose to fulfill in this life?
Too many people go through this life from birth to death and never find anything that moves them forward. It has been rightly said that all men die but that all men do not truly live.
Every Christian should find their first and most driving desire in life to be serving our Savior. There is no fiction in that statement. The lives of the people in this book called the passionates are people who found a purpose to live for that they never let go of as long as they lived.
You may be just an everyday, ordinary person as far as the world is concerned, but you were made by a loving Creator that did not make one other single person exactly like you. There may be people who look like you or sound like you. You may have spent your life trying to be like someone else. As you follow the lives of the people of this book, who did not ever live except in the imagination of one person, it is my hope that you will be able to see that a true passion can not only guide your life, but it can take you out of the humdrum of existence. The difference between you and these people is simple: you are real, and you are alive, and you can have a passion.
Just as these individuals never dreamed of what the special gift of an "eternity delayed" could be, neither will you be able to imagine what God can do in your life if it is driven by a passion that he sees as a noble endeavor.
Let your imagination free for a while and see what it could be like if you were driven by a passion that marks your very existence and converts your life into a life worth living. Remember, do not make any theological conclusions from this or any other work of fiction. This was not intended to be a children's book, but it is written so a child could follow the journeys of these people. But as C. S. Lewis said, a children's story that is not worth reading as an adult is probably not fit for children either.
Go and live your passion.
