“This is the reason why I have so often been hindered from coming to you.”
It must be very frustrating to be Satan.
Picture this: you are bound and determined to thwart the will of God, to destroy his work, to make null and void his promises, to corrupt his servants and taint everything he touches, to remake the world in your own image and to make your name greater than his.
And God beats you every time. With one almighty hand metaphorically tied behind his metaphorical back.
