I still haven't found what I'm looking for

I have been looking for a song for years, a song of me, a song tells my story. When did I first hear this song I can't remember, but without a second thought it was just another beautiful masterpiece of U2.

Today I played it again, all of a sudden an echo rose in my mind, turning stronger and stronger, finally occupies the whole heart of mine. So now I know, this is the song. A little ironically though, its name is I still haven't found what I'm looking for. Maybe that is why many previous searchings for a definite answer were doomed, and uncertainty is indeed all about it.

I have climbed the highest mountains
I have run through the fields
Only to be with you
Only to be with you

I have run I have crawled
I have scaled these city walls
These city walls
Only to be with you

But I still haven't found
What I'm looking for
But I still haven't found
What I'm looking for

I have kissed honey lips
Felt the healing in her fingertips
It burned like fire
This burning desire

I have spoken with the tongue of angels
I have held the hand of a devil
It was warm in the night
I was cold as a stone

But I still haven't found
What I'm looking for
But I still haven't found
What I'm looking for

I believe in the Kingdom Come
Then all the colours will bleed into one
Bleed into one
But yes I'm still running

You broke the bonds
You loosed the chains
You carried the cross of all my shame
All my shame
You know I believe it

But I still haven't found
What I'm looking for
But I still haven't found
What I'm looking for
