This is the acoustic part played for about half the song before the full band comes in:

Note: the high e string should not be open all the time, use your own discretion as to 
when to mute it and when not to.
e--0------000---000----000---000----000---000---00-00-00-00-|
B--3------333---33/5---555---55/7---777---778---88-77-55-33-|
G--0------000---000----000---000----000---000---00-00-00-00-|
D--5------555---55/7---777---77(b9)--99(b9)--99(b9)--9(b9)9(b9)77-55-|
A--3------333---33/5---555---55/7---777---777---77-77-55-33-|
E--x------xxx---xxx----xxx---xxx----xxx---xxx---xx-xx-xx-xx-|

This repeats throughout the whole song with minor variations, except that the fourth 
time it is played, this happens:
e--0------000---000----000---000----000---xxx---xx-xx-xx-x-|
B--3------333---33/5---555---55/7---777---xxx---xx-xx-xx-x-|
G--0------000---000----000---000----000---000---00-00-00-0-|
D--5------555---55/7---777---77(b9)--99(b9)--99(b9)--9(b9)9(b9)9(b9)(b9)|
A--3------333---33/5---555---55/7---777---70x---xx-xx-xx-x-|
E--x------xxx---xxx----xxx---xxx----xxx---xx7---77-77-77-7-|
and end on a harmonic over the 12th fret.

Then repeat the first riff.

I hope this helps people, I know this isn't super detailed or anything, but it should be 
enough to help out if you want to play along with the album or use it in a worship set.
