Fill this place with blood and that of no other
Than the Lord Jesus Christ
I am what I am, if it were not for mercy
I too would be damned, but by the grace of God
I stand in His righteousness, not of my own
To Him who worketh not but believes in Him alone
Fill this place with blood was told to Israel
Exodus from Egypt, Christ foretold in the passover
Romevo the leaven, true repentance
A thief on the cross, Jonah's second chance
Blood atonement is what God requires

Now notice closely
Slay the lamb, take a bunch of hyssop
Dip it in the blood, strike it on the door
It was not who was inside, did they do what God said
This is what matters so now believe Him
Blood atonement, is to be understood
Substitutionary death
You will either stand before God, bearing all of your sins
And pay the penalty, or let Christ stand there for you
As He did at Calvary to give you a gift
Justification, the gift of righteousness
