Cover art for Clean lyrics by This Beautiful Mess

This song is about the crucifixion of Jesus Christ. He went out there to carry the weight (of the sins of the world), to wear the crown of thorns (see Matthew 27:29 and John 19:2)... Because nobody here (in the world) is clean (without sin). "For all have sinned and fall short of the glory of God, and are justified freely by His grace through the redemption that came by Christ Jesus." -- Romans 3:23-24

"...Everybody is needing a scapegoat..." Jesus became our scapegoat when He died on the cross. He took the blame.

"...You're hit in the face, You're spit in the face..."
(see Matthew 27:30 and John 19:3)

So basically, we aren't clean but Jesus is clean (without sin). So He became our scapegoat, to save us.
