God want man to obey him, and husband want wife to obey him just as God want man to obey him so wife need to obey her husband.
Christ has died for us, and husband is like that to the wife he will die for the wife just as Christ died for us.
It's a great mystery, and that why wife need to obey there husband, and trust the husband as we trust God.
To the husband the wife flesh is conjoin, and is one with him what happen to his wife happen to him also the wife body is the same as the husband body so what your husband like about his body he also like about it on your body. If you get hurt your husband also get hurt. If he smack you he is also smacking himself.
Obey is all your husband really need if he say this do it right, and try not to mess up no matter the condition the more you impress your husband the better it is.
God said pray, and obey, and everything will be provided.
