The last book in "The Chronicles Of Narnia", is "The Last Battle." The 15th chapter is called "Further Up And Further In." Look no further for the inspiration for this song.
Lyrics
Day after day as my life unfolds before me
Week after week as the months go marching by
Life’s a blur and where I’ve been
I can never go back again
Here I go further up, further in
Week after week as the months turn into years
Year after year as the decades fly on by
There’s been laughter there’s been pain
I would never go there again
Here I go further up, further in
The way that is looks from where I stand
This road goes on and on and on with out end
Step after step as this journey leads me onward
Mile after mile as the next hill meets the sky
There’s been sunshine there’s been rain
Come to far to turn back again
Here I go further up, further in
Here I go further up, further in
