My belief is that God is His own cause and effect, and completely self contained.
In believing this, I accept that God is completely, "other," than us, his created beings. Therefore, God is unknowable by observation, but only by revelation.
He reveals to us, what He wishes us to know of Himself, to meet our needs for His own purposes.
We observe reality only through the five windows of our senses, and it is arrogant of Man to not only demand the right to know more, but to believe he has the capacity to understand the unknowable.
An amoeba could not understand us or our inventions, and God is far higher than us, than we are above the amoeba.
And before God created? Who knows? Who can know?
