I don't know how the stars hang
Or how there's night and then there's day
I don't know how you spoke into the black
And made it all obey

All I know is the bleeding in my heart
And the healing in your touch
All I know is that you gave everything
So let that be enough
'Cause it's all I know
[ Lyrics from: http://www.lyricsfreak.com/m/matt+wertz/all+i+know_20237345.html ]
I don't know how your love works
How you cover me in grace
I don't know how you swallow all I am
When I can't stand my taste

All I know is the bleeding in my heart
And the healing in your touch
All I know is that you gave everything
So let that be enough
'Cause it's all I know

I can't explain your mystery
But I know the answer

All I know is the bleeding in my heart
And the healing in your touch
All I know is that you gave everything
So let that be enough
'Cause it's all I know
