"My God is sooo powerful, that any morality he creates is objective"
"Okay, so the morality is subjective"
"No, it's objective, the god is sooooo powerful"
"That's not what objective means"
"You're not imagining how so, so powerful my God is. The problem here is your imagination"
It's basically Anselm's argument repolished.
Anyway, about your logical statement.
IF the God described in the Hebrew scriptures is real, then that God's laws are objective
I guess that the major issue I had was that the description of the god you seem to be pulling out of 'the Hebrew scriptures' does not jive with the description I am pulling out. So, your logical phrase should actually be.
IF the God I perceived as described in the Hebrew scriptures is real, then that God's laws are objective
Which, I'll grant, is harder to argue against. My beef with your logical statement is your understanding of that god's description. Our disagreement on the definition of 'subjective' and 'objective' are merely secondary.
