Key of E

I heard this song at CIY in Corvallis, Oregon and was very moved by it. It was sang by 
Bayless then, but the original is sung by Hillsong United.

E
Hallelujah,
     A2
Hallelujah,
     C#m
Hallelujah,
B       E
Our God Reigns (x8)

It can also be changed to the key of G

G
Hallelujah,
     C
Hallelujah,
     Em
Hallelujah,
D       G
Our God Reigns (x8)
