"She has absolutely no respect for me, is very rebellious toward me, and outwardly refuses to obey me in nearly every manner possible."
I have no respect for your either, you pompous, sef-righteous fart!
"She does not acknowledge that I have any authority over her."
You don't. Nor do you have any respect for her either!
"I have told her that she needs to obey me"
Listen up Bozo, NOBODY NEEDS to obey you. Are you on a power trip?
"... and leave it up to God to deal with me if I am wrong.
You are wrong. Leaving it up to God (assuming there is one) is hardly an option.
"I am heartbroken. I have been unable to make her happy in nearly everything for years. I feel that she needs a serious trial to bring her to her senses. "
You are heartbroken, so you will-wish her! What a loving person you are.
You need a divorce, and lose to her all your worldly possessions. Then you can utterly and completely deovte yourself to this crazy deity without having to worry about worldly trammels.
Have a nice day!
