Pretty awesome song, and nice and easy to have a little play with.

The chord progression for the verse is: E minor, A minor, C and D.
The chord progression for the chorus and outro: E minor, G, D and A minor.
You can just strum, finger pick, or whatever sounds good to you. :)

The toughest part, if you're singing and playing is just to get the timing right 
for the vocals, but even that isn't too difficult. Good luck! 

Em                 Am        C
So glad to see you have, overcome them
   D              Em
Completely silent now
                   Am
With heaven's help
                      C        D
You've cast your demons out
    Em               G          D            Am
And not to pull your halo-o-o-o down
 Em                 G            D           Am
Around your neck and tug you off your cloud
        Em               G
But I'm more than just a little curious
D                      Am                   Em          G    D            
How you're plannin' to go about makin' your amends
Am        Em       G       D
   To the dead
Am        Em
   To the dead

Em                               Am
  Recall the deeds as if they're all
       C
Someone else's
 D
Atrocious stories
Em
Now you stand reborn
          Am
Before us all
                   C             D
So glad to see you well

(Same as before with the chorus.)
And not to pull your halo down
Around your neck and tug you to the ground
But I'm more than just a little curious
How you're plannin' to go about makin' your amends
To the dead
To the dead


          Em     G           D          Am
With your haaaaaylo slippin' down
          Em G         D             Am
     Your halo slippin'
          Em G         D             Am
With your halo slippin' down
          Em G         D             Am
With your halo slippin' down
          Em G           D           Am
     Your halo's slippin' down 
             Em
To choke you now
