Beginning of the end (Why there is an end)

I was walking freely in the garden
Then by what vile presence, was I prohibited
Barred me from ever entering again?
Even giving up my eternal, yielded no pardon
With the spear in my cross anchored
Knowledge giving me only death and pain

How come then would a Creator
From the eternal screams of a thousands lambs
Give us life born from His splendour
To rock and condecend the Reaper's plans
Or to give birth to a fallen angels failure?
