Correction: you cannot have a debate with people who have set up their politics as a God.

In the scriptures God is depicted as someone who sometimes is willing to have a debate, and reason with people, of course not to learn anything, but to explain why things are (or must be) the way they are.

In some instances, God is even depicted as willing to listen to man and do things he otherwise would not have done, so long that they don't deviate from his fundamental purpose.
