It’s all words. There is no spiritual dimension in the sense that the spiritual is not a dimension of OUR universe and subject to it.
More appropriate would be that our universe is a result or dimension of the spiritual reality, or that both are a dimension or result of the Word of God.
Panentheism is not widely regarded as a heresy, never the less, that is not what I am even saying.
We are not in God (panentheism), but rather in his Word which created and sustains all things, physical and spiritual.
To say that physical causes then seem not “real” is getting hung up on the implicit assumption that a base physical reality is needed for something to be real. No…. “Real” is not defined as “existing apart from God’s sustaining power”. That’s just how it was defined by Aristotle, a Pagan, with a Pagan conception of God as part of the universe.
A base physical reality does not exist. Not even in physics (anymore). The reality of what we experience is “physical” in the sense that that is what we experience, but the reality is “sustained by the Word” which means it has no physical “essence” in itself… the Word is it’s only essence.
We can’t equivocate on this.
