The Battle Prelude is a song from Esther... The Girl Who Became Queen.
It was performed by Esther, talking about that God is on their side. It was from her Grandmother.
The battle is not ours
We look to God above
For He will guide us safely through
and guard us with His love
So do not be afraid
We need not run and hide
For there is nothing we can't face
when God is at our side
