That's sort of like saying "What you don't know can't hurt you." If it only weren't for all of those people who died not knowing what would kill them.
The reality is that gods are defined by people and explained by people. People end up claiming to have communed with gods, who deigned to favor them, and not everybody else, with their revelations. You are engaging in what I call the "ineffability defense". Whenever the believer encounters an argument against belief that cannot be overcome, the solution is to declare the object of belief "beyond understanding" and dismiss the argument. The ineffability defense never comes up when the believer is expounding at length on the comprehensible aspects of the alleged god. The ineffability defense is the ultimate "get out of jail free" card. It can be played whenever the player is in danger of losing.
Actually I am merely saying we have an incomplete understandg of God, for if God exists and is creator, then God must exist external from this universe and therefore not bound by it. Hence our understanding of God is limited. Limited by our binding to this universes. Limited by our own finite selves. However that limited understanding of God that we do have describes a perfect, infinite being that by that definition alone deserves our awe and worship.
Its nice to title an argument of which you disagree and dismiss it as if you nolonger need debate. But truth be told, you are partially correct. The grandness of God is such that nothing can stand in opposition to God, nothing can debate God. Its not a "get out of jail free" card, its an "automaticlly win" card. Of which there is no counterpoint only the choice to accept or not.
