Thanks to the comments from another guitarist on the version 1 I posted. Here is an 
updated and corrected version of the song along with the embellishments on the G chords.

The Well
Casting Crowns

Capo 1st Fret
INTRO

                  G
Leave it all behind
                  G
Leave it all behind
                  C
Leave it all behind
                  G
Leave it all behind

VERSE 1
                  G
I have what you need
But you keep on searching
                   Em
I've done all the work
But you keep on working
                        D
When you're running on empty
                        C
And you can't find the remedy
                   G   Gsus4  G
Just come to the well.

VERSE 2

                           G
You can spend your whole life
Chasing what's missing
                  Em
But that empty inside
It just ain't gonna listen
                   D
When nothing can satisfy
                          C
And the world leaves you high and dry
                   G   Gsus4  G
Just come to the well
 

CHORUS:

               C                   G
And all who thirst will thirst no more
             C                           G    Em    D
And all who search will find what their souls long for
                Am                   Em
The world will try, but it can never fill
                   C   D                  G    Gsus4 
 G
So leave it all behind, and come to the well

VERSE 3
                     G
 So bring me your heart
No matter how broken
                  Em
Just come as you are
When your last prayer is spoken
                  D
Just rest in my arms a while
                  C
You'll feel the change my child
                        G
When you come to the well

CHORUS:
              C                     G
And all who thirst will thirst no more
               C                          G    Em    D
And all who search will find what their souls long for
                Am                    Em
The world will try, but it can never fill
                    C  D                   G
So leave it all behind, and come to the well

     C        G
Yeah
                    C  G Em D
Leave it all behind
                Am                     Em
The world will try, but it can never fill
                C      D  C
So leave it all behind

                      G
And now that you're full
Of love beyond measure
                   Em
Your joy's gonna flow
Like a stream in the desert
              D
Soon all the world will see
                  C
Living water is found in me
                           G
‘Cause you’ve come to the well

CHORUS:
               C                    G
And all who thirst will thirst no more
               C                         G    Em    D
And all who search will find what their souls long for
                Am                     Em
The world will try, but it can never fill
                    C   D                  G
So leave it all behind, and come to the well
                    C   D                  G
So leave it all behind, and come to the well
