Thank you for clearly stating what I was trying to say. Logic is a fine thing, but it is utterly dependent on the premises. As humans - we do not choose our premises logically - let alone rationally.

Perhaps I was being fussy over the verb "contain", which to me suggests an envelopment, a designation of thinking as a sunset of logic.

Logic is a much broader subject than formal (Aristotelian) logic.
It includes mathematical logic, a formal calculus which permits the deduction of all mathematical principles (or nearly all) from a few postulates.B. Russell and C. N. Whitehead, Principia Mathematica It even includes a proof that mathematics is not compact and complete, and that some propositions may neither be proved nor disproved. It includes Boolean algebra -- derived from George Booles logic, the framework of computer circuitry.

"All men are dogs."
"Socrates is a man."
"Therefore, Socrates is a dog."

Is formally correct and shows that any proposition can be derived from a suitably false premise. If our premise is incorrect (and doubtless it is) then everything we derive from it is nonsense.

God is all powerful
God is within us, part of our souls
Therefore, we contain all power.
