For What Earthly Reason
For what earthly reason would the heavenly Father send down his Son
To suffer rejection and pay for crimes He had not done?
For what earthly reason would the Father let Him hang on a tree?
I wept with the answer, the one earthly reason was me.
Chorus
I was the reason, that one earthly reason;
I was the guilty, He was the sacrifice;
I was the taker, He was the giver,
Dying while I go free, That one earthly reason was me.
The fairest of angels were not summoned from the throne up in the sky
To purchase my pardon and not even the angels could die.
The only provision for my freedom was destined to be
The sweet Lamb of Glory, and His only reason was me.
