Only Know I Do lyrics

How do you explain the way the stars just
Hang way up in the sky
How do you explain the way rain goes away
Whenever you walk by

It's a mystery just how life can lead
To a place you've never been
You've knocked on that door
A hundred times before, when it
Suddenly let you in
[ Lyrics from: http://www.lyricsmode.com/lyrics/a/adam_gregory/only_know_i_do.html ]
I don't know why
I've been so blessed to love someone like you
I don't know why
I must confess, I only know I do

And how do you explain the way
My world has changed right before my eyes
And how do you explain the way you
Gave me wings
When I swore I could never fly

It's a mystery what you've done for me
I'm at a place I've never been
I've knocked on that door
A hundred times before
Now you've suddenly let me in

In my heart, I won't question
I'll just lay her in your arms
