God in His Simplicity- Indeterminate
Simplicity means... the quality or condition of being easy to understand or do.
Indeterminate means... not exactly known, established, or defined
So you believe God in his "condition of being easy to understand" is "not exactly known".
Whereas I believe Exodus 3:14 shows that God is exactly known as "the self-existent one".
Exodus 3:14... And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.
Here is an overview of what I believe...
Yahweh is spirit and is the only one who is eternal. Yahweh is also in the universe as spirit and as a human. Yahweh in the universe as spirit is called the Spirit of God, Yahweh in the universe as a human is called the Son of God, and eternal Yahweh is called God the Father.
