This one is quite straight forward, at least I hope it is. It is basically describing Jesus, His crucifixion, and the horrible torture He endured, all just to save us from our filthy lives. It's very saddening how this act of ultimate grace has gone unnoticed and unappreciated. As it says in the bridge, He never had to die for us. He as God could have just chose to not die on the cross and abandon us, yet He chose to die anyway because He knew it was what He was supposed to do and He was going to see it through no matter what.
