Ok so i love this song but this is not the original key it was sang in.  This is 6 down 
is in a singable range for many more people

Intro: Csus4 C  Am11 Am7  F6/9 F(+9) F6/9
       Csus4 C  Am11 Am7  F6/9 F(+9) 
F

Verse 1:
Csus2           C
Oh,what I would do to have
    Am11                Am7
the kind of faith it takes
                     F6/9    F(+9)
To climb out of this boat I'm in
Bb                 F
Onto the crashing waves
   Csus2           C
To step out of my comfort zone
Am11               Am7
Into the realm of the unknown
     F6/9    F(+9)
Where Jesus is,
Bb                 F
And he's holding out his hand

         G                 F
But the waves are calling out my name
         Csus4     C
and they laugh at me
    G           F
Reminding me of all the times
     Csus4               C
I've tried before and failed
      G                  F
The waves they keep on telling me
F       G   Am
time and time again
              Fsus2
"Boy, you'll never win,
         G
you'll never win."

Chorus:
C                     G                       Am
But the voice of truth tells me a different story
                Fsus4                   C
the voice of truth says "do not be afraid!"
C                       G/B                   Am
and the voice of truth says "this is for my glory"
                         Fsus2       F  F/G Am
Out of all the voices calling out to me
Am                 Fsus2                         Csus4
I will choose to listen and believe the voice of truth

(Repeat first line of intro)

Verse 2: (Chords are the same)
Oh, what I would do
to have the kind of strength it takes
To stand before a giant
with just a sling and a stone
Surrounded by the sound
of a thousand warriors
shaking in their armor
Wishing they'd have had the strength to stand

But the giant's calling out
my name and he laughs at me
Reminding me of all the times
I've tried before and failed
The giant keeps on telling me
time and time again
"Boy you'll never win,
you'll never win."

Chorus:
But the voice of truth tells me a different story
the voice of truth says "do not be afraid!"
and the voice of truth says "this is for my glory"
Out of all the voices calling out to me
Am                 Fsus2                           Ab
I will choose to listen and believe the voice of truth

Bridge:
Ab                             Bbsus
but the stone was just the right size
            Bb                 Ab
to put the giant on the ground
Ab                             Bbsus
and the waves they don't seem so high
         Bb                    Ab
from on top of them looking down
Ab                            Bbsus
i will soar with the wings of eagles
Bb                Fm7
when i stop and listen to the sound of Jesus
        G     C
singing over me

Chorus:
C                     G                       Am
But the voice of truth tells me a different story
                Fsus4     NC
the voice of truth says "do not be afraid!"
C                       G/B                   Am
and the voice of truth says "this is for my glory"
                         Fsus2       F  F/G Am
Out of all the voices calling out to me
Am7                Fsus2
I will choose to listen and believe (I will choose to listen and believe)
Am                  Fsus2       F
I will choose to listen and believe the voice of truth
