The Perils of Sloppy Wording

In his best-selling book Emotionally Healthy Spirituality, author Peter Scazzero writes:

When we leave reality for a mental creation of our own doing (hidden assumptions), we create a counterfeit world. When we do this, it can properly be said that we exclude God from our lives because God does not exist outside of reality and truth. (pp. 181-192 of the updated 2017 edition)

Now, I get what Scazzero is trying to say here. When we refuse to recognize the truth and reality of the way things are, but create our own preferred version of "reality" in our minds, we separate ourselves from God's truth and limit our own healing and wholeness until our thinking comes back into alignment with reality and the truth of God's word.

But saying that "God does not exist outside of reality and truth" seems to deny one of the chef classical attributes of God, His aseity-- His existence without dependence on anything or anyone. Scazzero's statement, as worded, could be taken to mean that God's existence is dependent on some concept of "reality and truth" that is outside himself. 

The fact of the matter is, God himself is the grounding of all reality and truth. Reality and truth depend on Him for their existence, not the other way around.

This may seem like a small quibble over semantics, and maybe I am being overly pedantic, but when we talk about the almighty Creator of everything else that exists, we must be careful how we say things.
