This is a tab my church uses in the verse. I think it's pretty funky :)
You start the tab where I have put "" in the lyrics (these are the chords we use)  
                                  
VERSE:
D (xx0232@1)                             BmWho (x24432@1)am I that you are mindful of me
              Em (022000@1)         DThat (xx0232@1)you hear me, when I call
D (xx0232@1)                              BmIs (x24432@1)it true that you are thinking of me
         Em (022000@1)                   CHow (x32010@1)you love me, it's amazing 
 
 
It sounds pretty cool with a delay on as well.
Wasn't sure about the difficulty rating, but any questions tweet me @_jowilliamson, peace out!
