There is no free moral agent in a marriage. No longer two but one. Her body belongs to him and his body belongs to her, until death. I’m not suggesting delivering the death penalty. It’s not even an eye for an eye. It’s merely exercising your authority, teaching a lesson, as the Bible permits. I don’t understand why Christians think we are supposed to be punching bags under every circumstance. Sometimes you have to stand up for what’s right, and singing songs doesn’t always work. At times perhaps the hands of God need to be the fists of God. I trust the Spirit will instruct me when that is necessary. In this instance the OP says the Spirit restrained him from doing so. Good for him to heed the voice of God. If there comes a time I am instructed otherwise, I have no reluctance in doing so. He has made vessels for many purposes.
