I don’t understand how you start out saying everything is black and white, and then start talking about shades of grey. You want to argue in absolutes, then disregard your own arguments as soon as it’s convenient to do so.
Some things are black and white and some things aren’t so simple. How come you see the world as incapable of being experienced in this way?
Perhaps it’s in the understanding that Satan is the father of all lies. Lies began somewhere, and it wasn’t with God.
So perhaps the “bigger” or “larger” lie Satan told, i.e.:
there is no God
I am God
you don’t need God
could be the “first” or “ultimate” “most important” lie just as well as the “larger” or “bigger” lie.
