The human race sinned and the penalty is death, but christ took our place and died that we may live: that is Love in display. Now a sincere Christian that is living right is doing that to appreciate the sacrifice made on calvary. Same with husband & wife. If the man has genuine love for her, a sincere woman will reciprocate.
The man is commanded to love his wife while the woman is commanded to submit to her husband. The problem is: Some men don't love their wives and they expect all the respect and submission. On the other hand, some women are not ready to submit but they want to be loved.
If husbands and wives can be sincere with themselves(the men doing the loving and the women doing the submitting, there will be so many sweet homes and the world will be a better place for us all.
