It's really easy, the whole song goes like this:  |  A  |  E  |  C#m  |  D7M  | 

A       E  C#m                D7M
Hi hello wake from thy sleep
A            E               C#m    D7M
God has given your soul to keep
A             E               C#m             D7M
all of the power that burns in the flame
     A          E            C#m    D7M
ignites the light in a single name
