Maybe you mean, "...Mark keeps going off on a tangent, always about the origin or the universe or origin of math."
Because, like all humanity wants to do, you look at this backwards. You see an unchangeable principle, that seems to you to be of its own derivation ("it just is"), but you can't prove it is of its own derivation, without negating first cause.
You go out of your way to show that there are things First Cause cannot do, yet you have done nothing to even show that a self-contradictory notion even is "a thing", i.e. a cause with effects. You go from there to imply this self-contradictory notion is a principle governing even First Cause, making even supposed 'first cause' an effect, and you even imply that this self-contradictory notion is not itself subject to external cause or principle.
What is logically self-contradictory is not in itself properly "a thing". The law of non-contradiction demonstrates that a self-contradictory notion is not "a thing".
If you mean, "Can he deceive you by telling you the truth?", yes, most certainly he can. Yet even that is a play on the facts, in that whom he thus deceives, are also deceiving themselves.
There are many things that God will not do. He will not, for example, contradict himself. He will be faithful to complete what he has begun. He will not change. He will not yield his glory to another. Etc etc. These do not limit God. They are, for lack of a better way for me to put it, 'of him' and not 'to him'.
You continue with this charade. The logically self-contradictory governs nothing. It does not limit God. Hello!
Let me try this: It is not because it is good to be good that God is good. Good-ness is what it is because God is good. He does not need to consider a supposed choice set before him, and then choose to do good. He does good because he is good. God does not answer to a principle we know of as "Existence". Existence is what it is because God exists. Reality is itself not able to govern God's existence. Reality proceeds from God, and is sustained by God.
Thus also: Logic is what it is BECAUSE God is logical.
Yet he does emanate it, or he is not God. God is subject, (as a bow to human terminology), only to himself, and not to any external principle.
The evidence is the coffee cup on your desk, the keyboard in front of you, the floor under you, and all other effects. If you deny first cause, you assert magic.
Again and again, ad nauseum, you assert that a self-contradictory notion is a governing cause.
Amazingly, not only do you consider us as possessing intellectual capacity to handle what by itself (though obviously self-contradictory) is a governing cause, and itself ungoverned, yet we, because of our great intellect, can manipulate it in our minds, but somehow God is always (and only) limited by it.
Logical necessity does not override God. You have not shown this. You've only shown a silly charade of supposedly logical progression, completely ignoring the fact that you are giving real status to a non-existent supposition.
"What is, is." What exists, has being. But what is self-contradictory does not have being. It does not "is".
Falsely proposed. There are things God will not do.
IF First Cause exists, all truth emanates from his point of view, and is expressed by him —not from our point of view, nor expressible by us.
I hope the day will come when you start to see how badly you play with words, and how God can so wisely play our game, using our terminology, yet do so in his OWN way, telling the truth we cannot understand, causing some to turn toward him and others to turn away, if only for that one instance. GOD is in charge, or he is not God.
