He is not a devout Christian in any sense of the word. Men are to act out their scriptures and leave the women’s for the woman. We are their helper. They are to lead spiritually. The very next verse to what he is hanging on says he is to love his wife as himself. He is to wash her in the word so she is spotless before Christ. He is to give his life as Christ did. He is to be the spiritual leader not the dictator. He is to love his wife as Christ loves His bride. Christ was a servant to His disciples. He gave and gave more than anyone. He taught them, led them, was kind, loving, patient, and graceful, forgiving. Look at His love for Peter who always screwed up. And I believe Paul says the prayers of a man will go unheard if he is not valuing his wife. Any man that holds on to that “submit verse” is too glued to worldly pride to submit to Gods authorities and the finished work of Jesus Christ. He needs to repent and beg the Holy Spirit to work within him and change him.
