From John Sander’s The God Who Risks:
To be consistent, the ideas within a model must “make sense,” since if they do not then they are literally “nonsense” and unintelligible. In order for a model to be intelligible, it must be logically consistent. Statements that are self-contradictory are meaningless. Symbolically, a contradiction is written A and not-A. That is, something that belongs in category A is also not in category not-A. If we say “my red car is not red” or “the apple on my desk is not an apple” we are not making meaningful utterances. Statements such as “God is the creator and is not the creator” and “God is timeless and also experiences time” are self-contradictory. They simply make no sense.
