The whole of Sacred Scripture teaches that God exists, because at the core of Sacred Scripture there is nothing but God, or the divine quality that comes from God. Scripture was dictated by God and nothing else can come from God except what is God and is called divine. This is what lies at the heart of Scripture.
In the derivative layers of Scripture that come from that heart and lie below it, however, Sacred Scripture has been adapted to the comprehension of both angels and people in the world. In these layers too there is divineness, but in different forms that are called heavenly, spiritual, and earthly divine qualities. They are in fact the layered clothes of God.
What God himself is like at the heart of the Word is something that cannot be seen by any created person or thing. When Moses prayed to see the glory of Jehovah, Jehovah replied that no one can see God and live [Exodus 33:20]. The situation at the heart of the Word is similar, where God exists in his own underlying reality and his own essence.
