Help with the Story of My Concept Album

Hey fellow proggers, I've been working on my own solo album from my home studio for quite some time now but I think I could use your help.  Most of the music is already written, but I'm working on the storyline for the concept at the moment.  I'm trying really hard to think of ways to make it better, as well as an ending, but I'm having trouble with ideas.  Maybe you can help.

Right now what I've got is (and I know it's a bit pretensious)...

The album opens with the end of the world, but the why or how is not revealed.  Strangly enough, everybody transcends with the exception of one person, though no reason is given why he does not.  He is stranded on Earth all by himself, with the sky stuck in an eternal grey, unable to escape, unable to die, with time frozen.  He spends his days staring into the vast ocean, with no way of escape.  The pattern is broken one day when for some unexplained reason he has a vivid dream of a utopian world, and is shown the way to the long forgotten Garden of Eden.  He makes his pilgrimage to Eden where he meets God (I told you it was a bit pretensious).  It is explained to him that creation and drestruction of Earth and it's population is not a one time occurance, but it has been happening and will continue happening indefinately.  He later finds that his Earth was the only one in which sin was allowed to enter.  He is forced to relive the terrible events that humans endured and put each other through, such as war.

From this point, I'm a little lost for ideas.  One thing I thought about doing was that he must re-enter either the next creation as a prophet, in order to prevent it from happening again.  Maybe the previous world could be recreated with his job to prevent sin from ever happening.  Maybe he must endure all of the punishment for all sin, sort of as an allusion to Jesus.

I'd drop the whole god thing.

An arguement for it ofcourse would be the cess pool of humanistic sin ... but against it would simply be love.
