I really don't like reading lyrics with chords interspersed, and they mess up search functions. Here's the Ronnie Bowman song with chords removed, a consolidation of lyrics from my post above, cleansed of the most glaring mistakes (but still of questionable accuracy).

Three Rusty Nails
Words and music: R. Bowman, J.Nettuno, T. Campbell

Two thousand years ago, you sent your son, you wanted us to understand
That whosoever would believe in him, would be safe in his hands

Chorus
With three rusty nails and an old dogwood tree
The sacrifice was made for you and me
We were afraid to say that he was the one.
What have we done to your son?

Oh how it hurts when someone laughs at you,
Their words can cut you like a knife.
Just think of all the shame we put him through
Guess he gave more than his life
Chorus

Well, we know not what we do,
we know not what we say;
We'll never know the price he paid
to take our sins away.
Chorus

With three rusty nails and an old dogwood tree
